D3 library in R?

I am working with the "r2d3" library in R (https://www.rstudio.com/blog/r2d3-r-interface-to-d3-visualizations/) - as I understand, this library is intended to perform javascript based data visualizations in R.
I would like to try and run the following visualization in R : https://rstudio.github.io/r2d3/articles/gallery/bubbles/
I loaded the data into R:
library(r2d3)
library(ggraph)
data(flare)
Then, I copied the entire "bubbles.js" script into a new R Markdown editor and clicked "knit to html". Then, I got the following output:
Clearly, I am doing something wrong.
Can someone please show me how to fix this?
Thanks!
Note: I tried running the following code in R Console:
r2d3(data = flare, d3_version = 4, script = "bubbles.js")
And this is the error I got:

/../as I understand, this library is intended to perform javascript
based data visualizations in R /../
It's more of an interface for existing D3 visualizations.
https://rstudio.github.io/r2d3/index.html provides fairly good overview of the process, you should go through that first.
To get that gallery sample working, you first prepare a working directory where you have:
flare.csv
bubbles.js
Once you have made sure your working dir is the same where those files are (getwed() / setwd()), running
library(r2d3)
r2d3(data = read.csv("flare.csv"), d3_version = 4, script = "bubbles.js")
in console / script / rmd should render those bubbles.
Or you could just clone the repo and have all sample files including Rmd-s - https://github.com/rstudio/r2d3/tree/main/vignettes/gallery/bubbles
RStudio provides some support for D3 scripts, so you can also go through File > New File > D3 Script and paste the bubbles.js content there or open existing bubbles.js file. Assuming you have flare.csv file in working directory, you can click on a Preview to have it rendered in Viewer pane. That's what the
// !preview r2d3 data = read.csv("flare.csv"), d3_version = 4
line in js script header is there for.

convert .obj to .glb using npm+laravel

I am stopped at one point for 2 days and not able to fix.
Can anyone please help me through this?
Question: How can I convert .obj file o .glb?
I used obj2gltf package of npm and search to implement it with Laravel but nothing helped. so now I am confused that does I am doing anything wrong?
Also I tried this article to use the node with PHP/Laravel and another solution from stack overflow.
Can anyone please help me through this?
Thank you in the advance guys.

Unfortunately, there is no solution in pure PHP. But you may create a JS script that converts your files using obj2gltf lib and then execute the script from the PHP in some kind of like that:
//php
$converter = '/path/to/your/script.js';
$objFilePath = '/path/to/your/3d.obj';
$glbFilePath = trim(shell_exec("node $converter $objFilePath"));
And let's say, your JS is converting your 3D object and then returning a path to the converted file:
// script.js
const obj2gltf = require("obj2gltf");
const fs = require("fs");
obj2gltf(process.argv[2])
.then(function (gltf) {
const data = Buffer.from(JSON.stringify(gltf));
fs.writeFileSync("result.gltf", data);
console.log(process.cwd() + "/result.gltf");
});

set file attribute filesystemobject javascript

I have created a file as part of a script on a network drive and i am trying to make it hidden so that if the script is run again it should be able to see the file and act on the information contained within it but i am having trouble doing this. what i have so far is:
function doesRegisterExist(oFs, Date, newFolder) {
dbEcho("doesRegisterExist() triggered");
sExpectedRegisterFile = newFolder+"\\Register.txt"
if(oFs.FileExists(sExpectedRegisterFile)==false){
newFile = oFs.OpenTextFile(sExpectedRegisterFile,8,true)
newFile.close()
newReg = oFs.GetFile(sExpectedRegisterFile)
dbEcho(newReg.Attributes)
newReg.Attributes = newReg.Attributes+2
}
}
Windows Script Host does not actually produce an error here and the script runs throgh to competion. the only guides i have found online i have been attempting to translate from VBscript with limited success.
variables passed to this function are roughly declared as such
var oFs = new ActiveXObject("Scripting.FileSystemObject")
var Date = "29-12-2017"
var newFolder = "\\\\File-Server\\path\\to\\folder"
I know ActiveX is a dirty word to a lot of people and i should be shot for even thinking about using it but it really is a perfect fit for what i am trying to do.
Please help.

sExpectedRegisterFolder resolves to \\\\File-Server\\path\\to\\folder\\Register which is a folder and not a file.
I get an Error: file not found when I wrap the code into a try/catch block.
I tested the code on a text file as well, and there it works.
So you're either using the wrong method if you want to set the folder to hidden.
Or you forgot to include the path to the text if you want to change a file to hidden.
( Edit: Or if Register is the name of the file, add the filetype .txt ? )
If you change GetFile to GetFolder as described in https://msdn.microsoft.com/en-us/library/6tkce7xa(v=vs.84).aspx
the folder will get hidden correctly.

Is there a way to AutoFormat (Javascript) code in TestComplete?

So similar to ALt-Shift-F in Netbeans, is there a to do this right in the ide in TestComplete? Not sure if this is possible or if anyone can think of a workaround to autoFormat without leaving the TestComplete window.
I'm trying to get the below solution to work with http://jsbeautifier.org/ for javascript / Jscript code in TestComplete.
Thanks

Great question!
There is no built-in function for that. So, we should not expect any solution to be 100% convenient - it is just not a simple task to modify the current script editor contents (if at all possible). So, whatever you do, it will still be some kind of compromise.
In general, the task is three-fold:
Get the current unit code.
Format the code.
Put the code back to the unit.
According to my understanding, items 1 and 3 can be accomplished only by creating a TestComplete plug-in - accessing editors for project nodes is not an easy thing.
UPDATE: silly me! There is a way to access the script editor code - I've updated the below part.
What will help us avoid switching to a different app, are the Script Extensions:
We create a custom Checkpoint in the form of a Script Extension, and install it to TestComplete. As a result, we get a button on the toolbar that we can click to invoke our code.
In the design time action, we call some code that reads the editor contents, then uses external code formatting functionality, and replaces the editor contents with the formatted code.
It would extremely interesting to see the implementations other TestComplete users can suggest! As a start, I am posting a solution that includes using an external web site to format VBScript code (http://www.vbindent.com/). I know that the starter of the post is probably using JScript, but I have not found a JScript formatter yet.
My solution is a simple Script Extension. I can't post a file here, so I will post the code of the two Script Extension files:
Description file:
<!-- Description.xml -->
<?xml version="1.0" encoding="UTF-8"?>
<ScriptExtensionGroup>
<Category Name="Checkpoints">
<ScriptExtension Name="VBScript Code Indent" Author="SmartBear Software" Version="0.1" HomePage="smartbear.com">
<Script Name="VBIndent.js">
<DesignTimeAction Name="Indent Current VBScript Unit" Routine="DesignTimeExecute"/>
</Script>
<Description>
Indents VBScript code in the currently active unit.
</Description>
</ScriptExtension>
</Category>
</ScriptExtensionGroup>
Code file:
// VBIndent.js
function DesignTimeExecute()
{
if (CodeEditor.IsEditorActive)
{
var newCode = IndentVBSCode_Through_VBIndent(CodeEditor.Text);
if (null == newCode)
return;
CodeEditor.Text = newCode;
}
}
function IndentVBSCode_Through_VBIndent(codeToIndent)
{
var URL_VBIndent = "http://www.vbindent.com/?indent";
var httpObj = Sys.OleObject("MSXML2.XMLHTTP");
httpObj.open("POST", URL_VBIndent, false);
httpObj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
httpObj.send("thecode=" + escape(codeToIndent));
var responseText = httpObj.responseText;
// Extract the indented code from the response
var rx = /<textarea name=\"thecode\".*?>((.*\n)*?)<\/textarea>/;
matches = rx.exec(responseText);
if (null == matches)
{
return null;
}
codeIndented = matches[1];
return codeIndented;
}
After you create these files, and put them to something like "\Bin\Extensions\ScriptExtensions\VBIndent", and click "File | Install Script Extensions | Reload", you will see a new "Indent Current VBScript Unit" item in the custom checkpoints drop-down button on the Tools toolbar. Clicking the element will format the VBScript code in the currently active editor.
So, this is to give a clear idea of what a solution can look like. Better suggestions are welcome! Share your thoughts!

random images from a folder

I am trying to rewrite my code below to search a folder for all the images (they will be numbered but there maybe gaps, ie not 1.jpg,2.jpg,3.jpg but instead 1.jpg,15.jpg,60.jpg for this reason i would like to search the folder, put all the images into an array and then pick one randomly each time its looped.
Any help would be greatly appreciated.
Firstly i am currently specifying image total above the main script below:
imgWidth = 160,
imgHeight = 95,
imgTotal = 22,
total = 0,
tiles;
//create the HTML for the tiles and append that to the bg element
function makeTiles(count){
var html = '', imgNum;
while(count--){
imgNum = Math.floor(Math.random()*imgTotal + 1);
html += "<div class='tile' style='background:url(public/images/portfolio/all/"+imgNum+".jpg) 0 0 no-repeat;' ><img style='opacity:0; filter:alpha(opacity=0);' src='public/images/portfolio/all/"+imgNum+"-c.jpg' alt='' /></div>\r";
}
$bg.append(html);
}

You'll need to create a list of available images with something else than javascript, since it has no filesystem access, even though in the end, you are accessing the images via their url.
Workaround: enable some directory listing for the images, then access this page via javascript, parse the image files and construct an array out of them; but frankly, there are shorter and more robust ways to accomplish this ...
pseudocode ..
$ ls -1 *jpg > imagesfilelist.txt
$ cp imagefilelist.txt /some/publicly/accessible/folder
js/jquery ..
$.get("/some/publicly/accessible/folder/imagefilelist.txt", function(data){
alert("My image files: " + data);
});
...

javascript can not access local folders. point.
I repeat: there is no way you can "search folder" to get "array of images" in JS. You could do that part (server only!) in PHP or such server-side language and return results via AJAX.

To do what you want you need to know what the images are called. JavaScript cannot access folder directly as commented above. You would need to use a server side script to provide an array of the images for the JS to pick at random to do this.

Javascript will not be able to browse folders. What you need to do is to create an array of available images and then select a random one. You could do this using any server side technology (php, rails, java, .net ...).

The way you're trying to do it is a wrong one.But iwth a bit of tricks it could work though, but it's very wrong way to do this kind of things.
You can generate file list with php and feed it to your script. You can even create php script which will generate your script already populated with needed data but it's not the best to do this too.
So, the best ways are:
- create html with list of filenames/images(visible or invisible) by php, then manipulate it by javascript;
- create html and javascript wich will do AJAX query to php script which will return filename list(formated as JSON if you wish).

Why not upload your images to a free hosting site (like Flickr) grab the feed from your image group and select the random image from there?
