R package workflow (assuming you're on macOS or Linux). You can chain commands `make check&&make install`. See also https://thierrymoudiki.github.io/blog/2024/08/30/r/makefile-r-pkg2.

Looks useful. But remove .Rbuildignore from clean. This is not an artefact.

A few other ideas at https://github.com/robjhyndman/forecast/blob/master/Makefile

@robjhyndman Thanks. Removed .Rbuildignore and added a few verbs, see:

Any other comment/suggestion is welcome.
