[R-pkg-devel] RES: MathJax for Rd files

Thanks, Wolfgang and Helmut for the explanations.
When I was trying to use

#'\if{html}{\out{'<script id="MathJax-script" async
#''src="https://cdn.jsdelivr.net/npm/mathjax at 3.0.5/es5/tex-chtml-full.js
#'</script> }}
#'
#'And then typing
#' \ifelse{html}{\out{\[\sqrt{a^2}\]}}{\deqn{\sqrt{a^2}}}
My mgidi.Rd file was produced with devtools::document();
then, I just used ?mgidi, and the html page was rendered nicely.

If I could do the same with mathjaxr, It would be nice, because I wouldn't need to install the package to see if the equations are as I expect
Anyway, mathjaxr is a very useful package.
Congratulations on the efforts for developing it.

Best
Olivoto

Thanks for the info! Can confirm now that I tried this (I don't usually use RStudio). That's an RStudio issue then. My guess is that 'Preview' uses tools::Rd2HTML() and that indeed won't automatically understand macros coming from mathjaxr (or any add-on package for that matter). This would be an issue to raise with the RStudio folks then.

But once a package is installed, the equations are nicely rendered also in the RStudio help browser, so that part works.

Best,
Wolfgang

Hi Wolfgang,

Seems like you are using roxygen2. I have little experience with 
that, as

all my Rd files are 'handcrafted' (plus 100% organic and biodegradable).

As are mine. ;-)
In the HTML-preview of RStudio the LaTeX is indeed not parsed. I get it 
only (in the HTML man-page and the PDF) if I build the package.
