Interesting. I gave this a try, but couldn't make this work. One would have to
infuse something like
<script id="MathJax-script" async

</script>
or
<script id="MathJax-script" async
src="<url-to-your-site>/mathjax/tex-chtml.js">
</script>
into the .html file, but just adding this to the .Rd file (directly or wrapped
with \if{html}{}) doesn't do that (it just gets printed). If somebody has
already successfully done this, I would be interested in hearing how.
You'd need to wrap that code in \out (inside the conditional, i.e.
something like
\if{html}{\out{<script id="MathJax-script" async
src="<url-to-your-site>/mathjax/tex-chtml.js"></script>}}

You can probably already do this using the \if{html} conditional, and
either including the matchjax js files in the package, or getting them
from a CDN.

Hello All,
I am wondering if there has ever been any discussion/consideration given
to incorporating MathJax (or something similar) into R for rendering
equations in .Rd files. I know that equations are rendered beautifully in
the pdf manuals, but I suspect the majority of users primarily look at the
html help files when using R. While I am comfortable reading something like
"B_x(a,b) = integral_0^x t^(a-1) (1-t)^(b-1) dt", it would definitely be
nicer if this was shown as a 'proper' equation.
Best,
Wolfgang
