Cannot import multiple r-script sources in RHTML visual
I'm unable to import multiple r-script source files in RHTML visuals. Power BI and R seem to import the first file referenced, but any subsequent source(./r_files/foo.r) calls appear to be ignored. This behavior is not getting repeated in RStudio using the same instance of R. Any guidance would be appreciated.
Steps to reproduce:
1) Create new visual using the RHTML template and create a new .r file in the r_files directory:
> pbiviz new sampleRHTMLVisual -t rhtml > cd sampleRHTMLVisual > echo $null >> .\r_files\test.r
2) Flesh out required information in pbiviz.json:
visual:description visual:supportUrl visual:author:name visual:author:email
3) Insert the following code as the first line in script.r:
source('./r_files/test.r')4) Compile and load the visual:
> pbiviz package
5) Observe the error message:
Can't display this visual.
R script error.
Error in libraryRequiredInstall("ggplot2"): could not find function "libraryRequireInstall"

Hello,
It is an issue in the template, we will fix it soon.
To fix it for you now, please, change NodeListOf by HTMLCollectionOf type. It should help.

[email protected]Confirmed. Changing the following seems to fix the issue:
./src/visual.ts
148 let headList: NodeListOf = el.getElementsByTagName("head"); > let headList: HTMLCollectionOf = el.getElementsByTagName("head"); 160 let bodyList: NodeListOf = el.getElementsByTagName("body"); > let bodyList: HTMLCollectionOf = el.getElementsByTagName("body");

Hello,
It looks like you try to create new project with non-webpack version of tools and it is probably required to set this file in tsconfig.json ('files' section).
I tried to build by your instruction with the latest version of powerbi-visuals-tools and everything looks OK.
To install the latest version of tools please run in a console the following command:
npm install -g powerbi-visuals-tools@latest

[email protected]Following the same set of instructions after installing the latest powerbi-visuals-tools package has two new errors during compilation.
Additionally, the same error occurs when simply running the following 3 steps:
