conda

Rough Notes

Easiest approach is to install pip within the conda environment and then using pip to install packages.
To install R, use conda install -c conda-forge r-base=4.1.2 r-essentials with the version number specification being very important.
Best practice for reproducible environments is to never install from conda or pip via the terminal, rather, add the required packages to the environment.yml file and update the environment when necessary.
