[R] reticulate + virtual environments

[Bert Gunter]

Have you tried https://rstudio.github.io/reticulate/  ?

Generally speaking, complex nonstandard package specific questions
such as yours rarely get a reply here -- there are 20,000+ packages
(and counting) after all! As reticulate was created by and integrated
with RStudio/Posit, I would think their site and help resources might
be a better venue. Of course, if you don't use RStudio, you may have
no joy there either.

Cheers,
Bert
