Hi Peter,

* gnu/packages/cran.scm (r-r2d3): New variable.

Unfortunately, I cannot merge this as is. This package contains a bunch of minified JavaScript files without the corresponding source code:

--8<---------------cut here---------------start------------->8---
r2d3/inst/www/d3/4.13.0/d3.min.js
r2d3/inst/www/d3/3.5.17/d3.min.js
r2d3/inst/www/d3/5.0.0/d3.min.js
r2d3/inst/htmlwidgets/lib/webcomponents/webcomponents.js
--8<---------------cut here---------------end--------------->8---

While we can easily replace the different d3 versions with non-minified source code that we then minify in a build phase, we cannot do this for webcomponents.js, which is compiled from TypeScript. The source code is
here:

    
https://github.com/webcomponents/polyfills/tree/master/packages/webcomponentsjs

webcomponents.js looks very similar to this blob:

https://github.com/webcomponents/webcomponentsjs/blob/v2.0.1/webcomponents-bundle.js

Arun is currently working on packaging swc, a transpiler that supports TypeScript, so with some luck we might then be able to transpile these
TypeScript source files to webcomponents.js.

It’s a bit more complicated than that. The source files import code from files in node_modules, which is supposed to be downloaded with npm. If we can identify these actual source files we could include them explicitly.
