roxygen2 & markdown & math

[Sigbert Klinke]

Hi,

I like to make my package documentation with markdown which is supported
since roxygen2 6.0.0 . I used a math expression like $t_n \appox N(0,1)$
which leads in the package check to "unknown macro '\approx'".

I guess I get the warning because math is not supported in markdown. Are
there any plans to support something like $...$ or $$...$$? Or there are
general problems?

Best Sigbert

Dear Sigbert,

The mathjaxr package provides this:

https://cran.r-project.org/package=mathjaxr
https://github.com/wviechtb/mathjaxr

Best,
Wolfgang

Hi,

thanks a lot, but maybe I was to vague.

I do not want to replace \eqn{...} and \deqn{...} by \mjseqn{...} and
\mjsdeqn{...}. I would like to use $...$ and $$...$$ as in Rmarkdown to
get something better readable.

a) This discussion is on the wrong mailing list. Please go to R-package-devel if you want to continue this discussion.

b) You can do whatever you want in your vignettes, but R doc files are designed to work with multiple output devices, including text-only terminals, so syntax specific to certain environments is not allowed. If you want to contribute improvements to R doc capabilities, I am sure patches will be considered as long as you adhere to the existing multi-platform constraints.

I think that's a question/suggestion that would have to go to the
roxygen2 team.  They're the ones who convert Markdown into the Rd input
format.  Presumably they could convert $...$ into the appropriate macro
using Mathjax or not, but I have no idea how difficult that would be.

If I remember correctly, I think it would be relatively hard since roxygen2
uses commonmark, which doesn’t include math in its parse tree. It might be
possible to hack something together with regular expressions, but of course
that brings with it the risk of introducing new edge cases that don’t
behave as expected.
