rpy2 and r-stringi support

[ayaby]

Two packages that would be useful to add are rpy2 (this worked only when I installed it from conda-forge) and r-stringi (which didn't work from conda-forge, only from r). The second is required as a dependency for quite a lot of packages, for example BayesFactor

Support for a python IDE that isn't jupyter lab would also be very useful (some basic functionalities are missing in jupyter lab)

Thanks!

I agree it might be useful at some point to add r-stringi - a few extra packages I needed relied on this for me too. Sometime, I'll have a go cloning the neurconda env & using makefile etc. to try contribute ...
