No. See ?setwd . It requires a dir argument and will therefore give an
error if one is not supplied. Nothing to do with "knowing" what the
current working directory is.

No (imho, anyway). Your working directory may change over time,
depending on how you organize things of course.
Please re-read the advice you have been given as well as ?startup.
