explicitly explaining setting of RENV_ROOT variable? #5

Open AltfunsMA opened 3 years ago

I was just confused by things only half working when I cloned the repo outside of my home directory (which has limited capacity). I ended up looking into the code and realised I needed to set the RENV_ROOT variable to the cloned folder. Maybe this is obvious to most people but perhaps could be mentioned in the README?

Renv currently expects to be installed in your home area, but as you discovered, you can set RENV_ROOT yourself if you installed it somewhere else. Here's a snippet from the Renv main script:

if [ -z "${RENV_ROOT}" ]; then
  RENV_ROOT="${HOME}/.Renv"
else
  RENV_ROOT="${RENV_ROOT%/}"
fi
export RENV_ROOT

You're right though, this should probably be documented somewhere useful.
