closed item set in data mining with R : I'm new to data mining with R and i want to find frequent itemsets of a data set using arules package .i found this example but it doesn't work for me .
ID=c("A123","A123","A123","A123","B456","B456","B456")
item=c("bread", "butter", "milk", "eggs", "meat","milk", "peas")
library(arules)
trans <- as(split(df$item, df$ID), "transactions")
the result that i want is :
# items transactionID
# 1 {bread,butter,eggs,milk} A123
# 2 {meat,milk,peas} B456
i'm getting this error :"Error in df$item : object of type 'closure' is not subsettable"
any idea for solving this error or another way for getting item set ??

How can I solve the error 'TS2532: Object is possibly 'undefined'? : <p>I'm trying to rebuild a web app example that uses Firebase Cloud Functions and Firestore. When deploying a function I get the following error: </p>
<pre><code>src/index.ts:45:18 - error TS2532: Object is possibly 'undefined'.
45 const data = change.after.data();
</code></pre>
<p>This is the function:</p>
<pre><code>export const archiveChat = functions.firestore
.document("chats/{chatId}")
.onUpdate(change => {
const data = change.after.data();
const maxLen = 100;
const msgLen = data.messages.length;
const charLen = JSON.stringify(data).length;
const batch = db.batch();
if (charLen >= 10000 || msgLen >= maxLen) {
// Always delete at least 1 message
const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
data.messages.splice(0, deleteCount);
const ref = db.collection("chats").doc(change.after.id);
batch.set(ref, data, { merge: true });
return batch.commit();
} else {
return null;
}
});
</code></pre>
<p>I'm just trying to deploy the function to test it. And already searched the web for similar problems, but couldn't find any other posts that match my problem. </p>

Jav- cant get "calculate again " to work. : I'm fairly new to Java so I'm having a hard time spotting my mistakes. I wrote a rock, paper, scissors game that had a play again feature. I thought I could copy it and it would work but it doesn't. This assignment is for a circle calculator. I got the main part to work I just need it to ask the user if they want to calculate another circle. Thanks in advance!
package circleapp;
import java.util.Scanner;
public class CircleApp {
static Scanner sc = new Scanner(System.in);
public static void main(String[] args) {
String answer;
String calcAgain;
do{
System.out.print("Enter a radius: ");
double radius = sc.nextDouble();
//Diameter=2*radius
double diameter= 2*radius;
System.out.println("Diameter: " + diameter);
//Circumference= 2*PI*radius
double circumference= Math.PI * 2*radius;
System.out.println( "Circumference: "+circumference) ;
//Area= PI*radius*radius
double area = Math.PI * (radius * radius);
System.out.println("Area: " + area);
//Would the user like to calculate again?
System.out.print("Would you like to enter another circle? (Y/N)");
calcAgain = sc.nextLine();
}
while (calcAgain.equalsIgnoreCase("Y"));

If statement doesnt work (python) : When I try to apply this if statement,
for i in (1,14197):
if (slope[i] <= 5):
slope[i]=0
nothing gets changed. I read that there might be a problem with the float type of the Dataframe. So one way would be to change the dtype and then apply the if statement. But isnt there a more elegant way? | 0debug |

Bogus float inequality due to compiler optimization? : <p>I found that some straightforward code results in an unexpected (and incorrect) inequality comparison on GCC 4.6.1 vs Visual Studio (2008 & 2012) or Clang 7.3.0 on OSX.</p>
<p>Here's a reduced snippet:</p>
<pre><code>typedef float ftype;
struct Foo
{
ftype v;
Foo(): v(16.0f / 60.0f) {}
ftype val() const {return v * 60.0f;}
};
void bar()
{
Foo f;
ftype v = f.val();
if (v != f.val())
printf("inequal");
}
</code></pre>
<p>If ftype is typedef'd as double then the problem doesn't occur. Could this be something to do with compiler inlining? Perhaps actually returning a double instead of a float?</p>

How to achieve test isolation with Symfony forms and data transformers? : <p><strong><em>Note:</strong> This is Symfony < 2.6 but I believe the same overall issue applies regardless of version</em></p>
<p>To start, consider this form type that is designed to represent one-or-more entities as a hidden field (namespace stuff omitted for brevity)</p>
<pre><code>class HiddenEntityType extends AbstractType
{
/**
* @var EntityManager
*/
protected $em;
public function __construct(EntityManager $em)
{
$this->em = $em;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
if ($options['multiple']) {
$builder->addViewTransformer(
new EntitiesToPrimaryKeysTransformer(
$this->em->getRepository($options['class']),
$options['get_pk_callback'],
$options['identifier']
)
);
} else {
$builder->addViewTransformer(
new EntityToPrimaryKeyTransformer(
$this->em->getRepository($options['class']),
$options['get_pk_callback']
)
);
}
}
/**
* See class docblock for description of options
*
* {@inheritdoc}
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'get_pk_callback' => function($entity) {
return $entity->getId();
},
'multiple' => false,
'identifier' => 'id',
'data_class' => null,
));
$resolver->setRequired(array('class'));
}
public function getName()
{
return 'hidden_entity';
}
/**
* {@inheritdoc}
*/
public function getParent()
{
return 'hidden';
}
}
</code></pre>
<p>This works, it's straightforward, and for the most part looks like like all the examples you see for adding data transformers to a form type. Until you get to unit testing. See the problem? The transformers can't be mocked. "But wait!" you say, "Unit tests for Symfony forms are integration tests, they're supposed to make sure the transformers don't fail. Even says so <a href="http://symfony.com/doc/current/form/unit_testing.html" rel="noreferrer">in the documentation</a>!"</p>
<blockquote>
<p>This test checks that none of your data transformers used by the form
failed. The isSynchronized() method is only set to false if a data
transformer throws an exception</p>
</blockquote>
<p>Ok, so then you live with the fact you can't isolate the transformers. No big deal? </p>
<p>Now consider what happens when unit testing a form that has a field of this type (assume that <code>HiddenEntityType</code> has been defined & tagged in the service container)</p>
<pre><code>class SomeOtherFormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('field', 'hidden_entity', array(
'class' => 'AppBundle:EntityName',
'multiple' => true,
));
}
/* ... */
}
</code></pre>
<p>Now enters the problem. The unit test for <code>SomeOtherFormType</code> now needs to implement <code>getExtensions()</code> in order for the <code>hidden_entity</code> type to function. So how does that look?</p>
<pre><code>protected function getExtensions()
{
$mockEntityManager = $this
->getMockBuilder('Doctrine\ORM\EntityManager')
->disableOriginalConstructor()
->getMock();
/* Expectations go here */
return array(
new PreloadedExtension(
array('hidden_entity' => new HiddenEntityType($mockEntityManager)),
array()
)
);
}
</code></pre>
<p>See where that comment is in the middle? Yeah, so for this to work correctly, all of the mocks and expectations that are in the unit test class for the <code>HiddenEntityType</code> now effectively need to be duplicated here. I'm not OK with this, so what are my options?</p>
<ol>
<li><p>Inject the transformer as one of the options</p>
<p>This would be very straightforward and would make mocking simpler, but ultimately just kicks the can down the road. Because in this scenario, <code>new EntityToPrimaryKeyTransformer()</code> would just move from one form type class to another. Not to mention that I feel form types <em>should</em> hide their internal complexity from the rest of the system. This option means pushing that complexity outside the boundary of the form type.</p></li>
<li><p>Inject a transformer factory of sorts into the form type</p>
<p>This is a more typical approach to removing "newables" from within a method, but I can't shake the feeling that this is being done just to make the code testable, and is not actually making the code better. But if that was done, it would look something like this</p>
<pre><code>class HiddenEntityType extends AbstractType
{
/**
* @var DataTransformerFactory
*/
protected $transformerFactory;
public function __construct(DataTransformerFactory $transformerFactory)
{
$this->transformerFactory = $transformerFactory;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->addViewTransformer(
$this->transformerFactory->createTransfomerForType($this, $options);
);
}
/* Rest of type unchanged */
}
</code></pre>
<p>This feels ok until I consider what the factory will actually look like. It will need the entity manager injected, for starters. But what then? If I look further down the road, this supposedly-generic factory could need all sorts of dependencies for creating data transformers of different kinds. That is clearly not a good long-term design decision. So then what? Re-label this as an <code>EntityManagerAwareDataTransformerFactory</code>? It's starting to feel messy in here.</p></li>
<li><p>Stuff I'm not thinking of...</p></li>
</ol>
<p>Thoughts? Experiences? Solid advice?</p>

How to get only the value from an array of objects in javascript with out mention it's key? : <p>I have an array of object like:</p>
<pre><code>var customerArr = [
{
name:'Tarmizi',
address: 'Bintaro'
},
{
name:'Imam',
address: 'Pejaten'
},
{
name:'gugi',
address: 'Depok'
},
{
name:'een',
address: 'Bintaro'
}
];
</code></pre>
<p>The result I want to is: </p>
<pre><code>Tarmizi
Imam
gugi
een
</code></pre>
<p>I can get the result like above with:</p>
<pre><code>for(customer in customerArr){
console.log(customerArr[customer].name);
}
</code></pre>
<p>But in my case the object of array I get from json array by uploading excel file with header has space.</p>
<p>So, I need to get the value of array with out mention of it's key.</p>
<pre><code>for(customer in customerArr){
console.log(customerArr[customer].name <-- with out .name);
}
</code></pre>
<p>Thank a lot before</p>

How to switch between two activities? : I have two activities 1. rfidReaderActivity 2.TravelActivity
When I read the card i go to the TravelActivity and calculate startingLocation(latitude,longitude) and go back to previous activity(rfidReaderActivity)
Then again when i read the card I need to go to the TravelActivity and this time i will calculate destination and distance traveled.
So how it can be done to switch between them, considering that the TravelActivity is not destroyed.
Please explain, i have poor understanding about activityLifecycle.

How to use a two dimensional array in function declaration statement? : <pre><code>void sort(int [],int);
</code></pre>
<p>This is how I usually use a single dimensional array(i.e: <code>int []</code> ) inside a function declaration statement for programs like sorting and it works fine without any problem</p>
<p>But for my matrix addition program when I use a two dimensional array(i.e:<code>int [][]</code> ) inside a function declaration statement with the similar format <code>void mat(int [][],int [][],int ,int);
</code>Iam getting some error messages like:-</p>
<p>1.multidimensional array must have bounds for all dimensions except the first.</p>
<p>2.invalid conversion from 'int (*)[10]' to 'int' [-fpermissive].</p>

React stateless component this.refs..value? : <p>I don't know if I'm doing this correctly...
If I want to get value from an input I use this.refs.whatever.value.trim() but if that input is a stateless function component how do I do retrieve the value onSubmit?</p>
<p>I know this isn't correct now after researching but how are you supposed to get value from these input fields?</p>
<pre><code>import React, {Component} from 'react'
import {InputField} from '../components/forms/InputField'
import {Button} from '../components/forms/Button'
export default class SignupWrapper extends Component {
_handleSubmit(e) {
e.preventDefault();
const email = this.refs.email.value.trim();
const password = this.refs.password.value.trim();
const confirm = this.refs.confirm.value.trim();
console.log({email, password, confirm});
}
render() {
return (
<form id="application-signup" onSubmit={this._handleSubmit.bind(this)}>
<InputField type={'email'} name={'email'} text={'email'}
helpBlock={'email is required'} ref="email" />
<InputField type={'password'} name={'password'} text={'password'}
helpBlock={'password is required'} ref="password" />
<InputField type={'password'} name={'confirm'} text={'confirm password'}
helpBlock={'password confirmation is required'} ref="confirm" />
<Button type={'submit'} className={'btn btn-primary'} text={'signup'} />
</form>
)
}
}
</code></pre>
<p>this is the stateless inputfield</p>
<pre><code>import React from 'react'
export const InputField = (props) => (
<div className="form-group col-xs-12">
<label htmlFor={props.name}>{props.text}</label>
<input type={props.type} name={props.name} className="form-control"
data-stripe={props.stripe} />

How to get mac addresses of clients connected to a router through an external request : <p>The situation is that I have to scan mac addresses of clients(portable ones) connected to multiple routers. I want to set up a server that can make an external request (or some networking tool to scan) all the routers to fetch the required data.</p>
<p>P.S.: I do know about nmap scan, but for that, the server also has to be connected to same router, and I can't fetch/scan from other routers.</p>

so as you can see this is all in sequence, but now i want to achieve all trimmed zeros, like if this number got any zero, it should move to next sequence which is not having zero.
Like if it after moving ahead of 9, it shouldn't show 10 instead it should show 11,
1,2,3......8,9,11.....19,21....59,61.....99,111.... because 101, 102 again including zeros, so it should be having 111 directly.
then 198,199...211.... as can't keep 201,202. go gaps are undefined. not an fixed interval. tried a lots things. getting closer but not correct at all.
**Output i want :**

for (int i = 5; i >= -5; i--)
{
result = i >= 0 ? i : -i;
Console.Write("{0}\t", result);
}
output:

How to Do Histogram Equalization in Imagesc's 3 Parameters of Matlab? : Situation: do histogram of the presentation in `imagesc(time,potential,C)` by using `time`, `potetial` and/or `C`; do normalized histogram equalization in the histogram
Proposal: I think `C` is the data for the histogram because `time` and `potential` are just equispaced-equidistant vectors for x- and y-axis, respectively
Code and pseudocode
time=linspace(0,50,100 + 1);
potential=linspace(0,50,100 + 1);
C=gallery('wilk',21); % tridiagonal matrix, eigenvalue problem, Wilkinson 1965
figure, imagesc(time,potential,C);
%% Output: Tridiagonal image
%% Histogram Equalization Pseudocode
% Draw here the histogram of time, potential and/or C
C=histogram_equalization(C,...);
figure, imagesc(time,potential,C);
%% Expected output: tridiagonal image after histogram equalization
Observations
- `C` is not an intensity image because `figure, imhist(C)` returns blank output
- I may need to consider `time` and `potential` also when considering the histogram of `C`. However, they are just equally spaced vectors for the axes so it should not be necessary.
Unsuccessful attempts
- RockTheIT's [code][3] is based on the image handler (`hFig`) or reading .png images. You cannot just put `I=C`, although `I` is a matrix. Why?
- `hist` attempt based on the thread [Difference between hist and imhist][4] gives blank image in `imagesc(x,y,C)` where I am trying to plot all contents of `C` for histogram
C = hist(double(C(:)), 256);
Signal Processing
- Gonzales says the *normalized histogram is given* by $p(r_k) = r_k / M N$, for $k = 0,1,2,...,L-1$ where
- intensity levels ranges in $[0,L-1]$,
- $p(r_k)$ is an estimate of the probability of occurrence of intensity $r_k$ in an image,
- $MN$ is the product of the pixel sizes in `time` and `potential`, respectively

tweepy : ow get more than 100 different record per day per query using Twitter Standard API? : I'm trying to download a list of tweet using the standard API but what I get are always the same records.
i.e. this is my request:
```
ApiSearch = api.search(q="#immigration", lang="en", result_type="mixed", count=100, until=untilDate, include_entities=False)
```
but if I run it now and then between 1 hour the result I get is the same.
Is there something wrong in the settings of my "api.search", or did I misunderstood the limits of the Twitter Standard API?
This is my code:
```

"PWD=pswd;"
"SERVER=localhost;"
"PORT=5432;")
consumer_key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

access_token = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
access_token_secret = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

Why does P != "P" in my JSON response? : <p><strong>QUESTION:</strong></p>
<p>For some strange reason, it seems "P" from my JSON is not equal to "P" but "P"=="P" returns true. This makes no sense.</p>
<p>There must be some data type issue somewhere.</p>
<p>How can I make sure <code>response.charAt(0) == "P"</code> returns <code>true</code> ?</p>
<hr>
<p><strong>CODE:</strong></p>
<pre><code>$.ajax({
type: "POST",
url: "/1/1",
data: someData,
}).done(function(response) {
console.log("p" == "P"); //prints false
console.log("P" == "P"); //prints true
console.log("RESPONSE: "+response); //prints "Primary"
console.log("RESPONSE FIRST LETTER: "+response.charAt(0)); //prints P
console.log("RESPONSE BOOL P :"+response.charAt(0)=="P");
//
//false for some reason, should be true
//
if (response.charAt[0] == "P") {
console.log("1");
localStorage.setItem("error_msg_local", message);
} else if (response.charAt[0] == "L") {
localStorage.setItem("success_msg_local", message);
console.log("2");
} else {

How to return -1 value? : <p>Write a function called day_diff that takes four scalar positive integer inputs, month1, day1, month2, day2. These represents the birthdays of two children who were born in 2015. The function returns a positive integer scalar that is equal to the difference between the ages of the two children in days. Make sure to check that the input values are of the correct types and they represent valid dates. If they are erroneous, return -1. An example call to the function would be</p>
<blockquote>
<blockquote>
<p>dd = day_diff(1,30,2,1);

Python enumerate reverse index only : <p>I am trying to reverse the index given by <code>enumerate</code> whilst retaining the original order of the list being enumerated.</p>
<p>Assume I have the following:</p>
<pre><code>>> range(5)
[0, 1, 2, 3, 4]
</code></pre>
<p>If I enumerate this I would get the following:</p>
<pre><code>>> list(enumerate(range(5)))
[(0, 0), (1, 1), (2, 2), (3, 3), (4, 4)]
</code></pre>
<p>However I want to reverse the index provided by enumerate so that I get:</p>
<pre><code>[(4, 0), (3, 1), (2, 2), (1, 3), (0, 4)]
</code></pre>
<p>So far I have the following code:</p>
<pre><code>reversed(list(enumerate(reversed(range(5)))))
</code></pre>
<p>I was just wondering if there was a neater way to do this?</p>

Finding values in one column with several different values in another column in R : I have a large data set with a column for the identity and a birthdate. Unfortunately, some id names were used for different individuals.
`sample = data.frame("id" = c("val1", "val1", "val1", "val1", "val2", "val2", "val2", "val3", "val3", "val3", "val3"),
"birthday" = c("1", "1", "1", "1", "2", "3", "4", "5", "6", "7", "7"))`
Now I'm trying to find which id's have different birthdates to be able to rename them.
I know I could do it with a for loop but I was wondering whether there is an easier & faster way? Or how would you deal with it?
Thank you very much
Nina
