Get pid (process ID) of R session from within R session (to attach a debugger)

问题

How can I find out the process ID of the current R session my R code is running in?

I am using Ubuntu 18.04, but an answer working on Windows would also be great.

回答1:

There is a command called Sys.getpid() that outputs the session ID directly

Sys.getpid()
