kandi X-RAY | correlation Summary
correlation is an easystats package focused on correlation analysis. It’s lightweight, easy to use, and allows for the computation of many different kinds of correlations, such as partial correlations, Bayesian correlations, multilevel correlations, polychoric correlations, biweight, percentage bend or Sheperd’s Pi correlations (types of robust correlation), distance correlation (a type of non-linear correlation) and more, also allowing for combinations between them (for instance, Bayesian partial multilevel correlation).

QUESTION
I wish to create a Space Adjacency Matrix in R, preferably using ggplot/tidyverse for consistency with other scripts, but I am open to other solutions.
A Space Adjacency Matrix is used in interior and architectural design to illustrate relationships (adjacencies) between spaces within a building.
Each space in the building has a relationship (or lack of relationship) to every other space.
The input data is likely formatted similarly to this:

Answered 2022-Apr-11 at 17:14I don't know of any package that implements this. But it is good to keep in mind that you can basically plot anything in ggplot2, as long as you can translate what you're plotting to polygons. That said, here is how you can translate this particular problem to polygons.

QUESTION
I am using fetch in a NodeJS application. Technically, I have a ReactJS front-end calling the NodeJS backend (as a proxy), and then the proxy calls out to backend services on a different domain.
However, from logging errors from consumers (I haven't been able to reproduce this issue myself) I see that a lot of these proxy calls (using fetch) throw an error that just says Network Request Failed, which is of no help. Some context:
- This only occurs on a subset of all total calls (lets say 5% of traffic)
- Users that encounter this error can often make the same call again some time later (next couple minutes/hours/days) and it will go through
- From Application Insights, I can see no correlation between browsers, locations, etc
- Calls often return fast, like < 100 ms
- All calls are HTTPS, non are HTTP
- We have a fetch polyfill from
fetch-ponyfillthat will take over iffetchis not available (Internet Explorer). I did test this package itself and the calls went through fine. I also mentioned that this error does occur on browsers that do supportfetch, so I don't think this is the error. - Fetch settings for all requests
- Method is set per request, but I've seen it fail on different types (GET, POST, etc)
- Mode is set to 'same-origin'. I thought this was odd, since we were sending a request from one domain to another, but I tried to set it differently and it didn't affect anything. Also, why would some requests work for some, but not for others?
- Body is set per request, based on the data being sent.
- Headers is usually just
AcceptandContent-Type, both set to JSON.
I have tried researching this topic before, but most posts I found referenced React native applications running on iOS, where you have to set some security permissions in the plist file to allow HTTP requests or something to do with transport security.
I have implement logging specific points for the data in Application Insights, and I can see that fetch() was called, but then() was never reached; it went straight to the .catch(). So it's not even reaching code that parses the request, because apparently no request came back (we then parse the JSON response and call other functions, but like I said, it doesn't even reach this point).
Which is also odd, since the request never comes back, but it fails (often) within 100 ms.
My suspicions:
- Some consumers have some sort of add-on for there browser that is messing with the request. Although, I run with uBlock Origin and HTTPS Everywhere and I have not seen this error. I'm not sure what else could be modifying requests that would cause it to immediately fail.
- The call goes through, which then reaches an Azure Application Gateway, which might fail for some reason (too many connected clients, not enough ports, etc) and returns a response that immediately fails the
fetchcall without running the.then()on the response.
For #2, I remember I had traced a network call that failed and returned Network Request Failed: Made it through the proxy -> made it through the Application Gateway -> hit the backend services -> backend services sent a response. I am currently requesting access to backend service logs in order to verify this on some more recent calls (last time I did this, I did it through a screenshare with a backend developer), and hopefully clear up the path back to the client (the ReactJS application). I do remember though that it made it to the backend services successfully.
So I'm honestly not sure what's going on here. Does anyone have any insight?
...ANSWER
Answered 2022-Jan-25 at 15:48Based on your excellent description and detective work, it's clear that the problem is between your Node app and the other domain. The other domain is throwing an error and your proxy has no choice but to say that there's an error on the server. That's why it's always throwing a 500-series error, the Network Request Failed error that you're seeing.
It's an intermittent problem, so the error is inconsistent. It's a waste of your time to continue to look at the browser because the problem will have been created beyond that, either in your proxy translating that request or on the remote server. You have to find that error.
Here's what I'd do...
Implement brute-force logging in your Node app. You can use Bunyan, or Winston or just require(fs) and write out to some file when an error occurs. Then look at the results. Only log it out when the response code from the other server is in the 400 or 500 ranges. Log the request object and the response object.
Something like this with Bunyan:
QUESTION
I have a list of data in a visualisation and I want to make it as accessible as possible. There are two lists next to each other.
The list items has two states. Multiple rows can be active or inactive. A single row could be selected.
Selecting something in one list, will show 'related' items as active, and inactive. See the simplified example below. The user has selected "A 2", which is linked to "B 1" and "B 4", so A2 is aria-selected but there's no aria-active or aria-inactive, I thought to use aria-disabled as demonstrated - BUT does this not indicate that it is not interactable? The user can still click on the disabled item to then select it.
Would it be better to do multiple aria-selected, and a single aria-current=true on the single 'selected' item? Would it be odd that if the user hasn't yet made a selection and everything is 'active', every item will be aria-selected=true?
ANSWER
Answered 2022-Jan-14 at 23:31From a semantics and accessibility point of view, I'd consider separating out the controls from the visualization itself—at least in terms of the markup. This will let you use more semantic input elements, like , which come with their own states that assistive tech understands. And it will keep selection state (which is an input element trait) separate from highlighted state (which is a visualization display trait).
You can then tie those input elements to the visualization using the aria-controls attribute.
To denote the state of the items in the visualization itself, instead of using ARIA roles, I would suggest just using text.
A basic example could work something like this:

This only applies to Visual Studio 2022. I had uninstalled VS2019 and Preview where F# worked absolutely fine (F# 5.0). I am using VS2022 to use F# 6.0 and do not want to go back to F# 5.0.
The issue is specific to F#. I also use C# and I have no issues running the latest C# under VS2022.
There are near continual DevEnv processes running consuming anywhere from 1 to 4 of my CPU's 4 Hyperthreads. I have switched off all experimental options I can find in F# settings.
Sometimes there are 2 or more background processes running , sometimes paused and sometimes none - there appears to be no correlation between this and the background CPU consumption
Sometimes I have a pop up Dialog about waiting to complete an editor process or a compile process.
When devenev.exe is consuming CPU cycles under the properties I see there is always one clr.dllCoUnInitializeEE+0x6790 that is the culprit. I though this was meant to be a short-lived process? Sometimes there are two or three of these consuming most of a HyperThread (There are identical others but with very low or no CPU consumption). The stack on the guilty thread is as follows:
