Comment (by barracuda156):

 Replying to [comment:1 jmroot]:
 > Same question for several other R ports actually.

 I am generally relying on CRAN info (which apparently just parses
 DESCRIPTION file from the source): it says whether compilation is needed
 or not.
 For example, `mathjaxr` is supposed to have compilable files:
 https://cran.r-project.org/web/packages/mathjaxr/index.html
 And indeed, upstream repo has `src` folder (which carries non-R sources,
 normally C/C++/Fortran): https://github.com/wviechtb/mathjaxr
 It is surprising if it does not install anything of those.

 I did see a few cases where CRAN info was inaccurate, perhaps due to
 developers being careless and not specifying that a package is R-only. So
 it is not 100% reliable.

 I have no idea whether R packages install non-identical R files across OS
 versions and platforms and whether that is always consistent. If someone
 could confirm that is strictly the case, adding a line for platforms won’t
 be hard, as long as `noarch` always implies `{darwin any}`.
