Downloading r scripts on-the-fly

Anonymous — Mon, 16 Sep 2019 20:57:46 GMT

I'm attempting to create a custom visual that downloads r scripts on-the-fly, but am running into a challenge with getting it to work in the Power BI Service.

I've created a custom visual based off the RHTML template that is supposed to plot a graph, but I wanted to solve for a solution where our analysts can maintain & tweak their models without having to recompile the Power BI visual. On the desktop, this seems to work wonderfully when I add have the following code in my script.r file and modelpath is a string parameter that is the URL to my file.

#Import web file if path is defined
if(modelpath != ""){
  source(modelpath)
}

I'm able to post an r script to github and Power BI Desktop (along with R) are able to download and import the file from github. When I attempt to use this same visual with the online Power BI service, I get the following error:

In file(filename, "r", encoding = encoding) :

  InternetOpenUrl failed: 'The server name or address could not be resolved'


Please try again later or contact support. If you contact support, please provide these details.

Does anyone have any suggestions?
