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. 

Rdpack::viewRd() can be of some help but it currently loads only the RdMacro's from its package.

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.
