Reticulate made switch between R & python easy, and doing its best to facilitate both worlds of data science.

Meanwhile, I noticed that most of my followers or students raised the issues of uneasy switch between

different python versions or virtual environments in RStudio while using repl_python() .

Here is my nimble tweak, hope, RStudio will come up with a better solution in coming days as in Spyder’s (pointing to interpreter).

As, most of us use, Rprofile.site which will be available in ~/R/etc folder for setting R environment variables,

exploit the same for setting needed python version or virtual environment:

# python version

Sys.setenv(RETICULATE_PYTHON = “~/python37/python.exe”)

# python virtual environment

Sys.setenv(RETICULATE_PYTHON = “~/envs/stan_env/python.exe”)

Currently, commenting and un-commenting needed version in Rprofile.site, and restarting session

seems to be not a bad nimble tweak for bringing up needed python environment in RStudio.
