Example with r-conda and CRAN/MRAN

[jamesmyatt]

Do you have an example that uses both conda (for R and/or Python) and installs extra packages from CRAN/MRAN? i.e. the R version of https://github.com/binder-examples/python-conda_pip.

Hi, I have a similar question as above. Specifically, you mention in your readme that we can install CRAN/MRAN files into a Python conda environment with a postBuild script. I was wondering if you could provide an example of this? Thanks!
