Cannot import multiple r-script sources in RHTML visual

Anonymous — Tue, 13 Aug 2019 20:47:40 GMT

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"
Execution halted

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

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:

> pbiviz new sampleRHTMLVisual -t rhtml
> cd .\sampleRHTMLVisual\
> pbiviz package

> pbiviz package

Is it possible to share a link to your repo that I could analyze it?

You could send it to pbicvsupport@microsoft.com

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.

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");

What is your complete line of code in row 148? The table in this webpage wrapped each line of text into two rows, but they should just be one row each in visual.ts

Row 148 should read:

let headList: HTMLCollectionOf<HTMLHeadElement> = el.getElementsByTagName("head");

Row 160 should read:

let bodyList: HTMLCollectionOf<HTMLBodyElement> = el.getElementsByTagName("body");
