[R-pkg-devel] MathJax for Rd files

I don't know if this helps but I have the following note in  viewRd() (from 2017!) at https://github.com/GeoBosh/Rdpack/blob/81af94d0e690b9f02275e89d474ce184d63fb044/R/bib.R

...
    ## TODO: (BUG) e is NULL under RStudio
    e <- tools::loadPkgRdMacros(system.file(package = "Rdpack"))
## Rdo <- parse_Rd(infile, macros = e)
...

Maybe I have forgotten to delete the note after fixing that since it works  (I just checked in Rstudio) but maybe that's the reason I restricted it to just macros in Rdpack.

The issue is not with Rstudio per se but that in devtools' development mode  help() is modified to show the Rd files in the source directory, as one would expect, but doesn't load the RdMacros. So, the issue appears when one is development mode.

Yes, the error appears to be in the pkgload::load_rd_macros() 
function
here:
https://github.com/r-lib/pkgload/blob/1b1adc39628671f2ea4256f0bebcdb76e1f89f45/R/dev-help.r#L47.

It doesn't look at the DESCRIPTION file to see if there's an RdMacros entry.

Isn't that what tools::loadPkgRdMacros() does there? I believe so.

Yes, you're right.  So it's not clear why the preview isn't working.
