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.

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