Hooks with
language: rfail under certain circumstances if there is a virtual R environment present in the repo where a user want's to use hooks. This is because the env variableRENV_PROJECTis set in the terminal by some editors, e.g. RStudio to the virtual R environment of the user, but when pre-commit installs hooks (from that IDE terminal), it should not use that environment (obviously). Hence, we should unset that env variable before installing hooks. See rstudio/renv#900 for an in-depth discussion.In addition, the command line executable
Rscriptshould not be used when called from R itself for some version incompatibility, but instead in that case, the full path should be specified. Hence, if$R_HOMEis set, we should construct the full path to the executable with it, instead of relying on the$PATH.
