I got a different error than yours

It seems that emacs shell is not run on a tty? (I am not an emacs user, not sure about it)

Anyway, your error is because the terminal width cannot be determined and 0 is returned. e7a6d89 should have fixed it. Try installing the development version and see if it fixes your issue.

Thanks a lot, it fixed the error, the only problem I have right now is that the R prompt disappeared (see screenshot). It's usable and thanks again for the quick fix.

It seems emacs shell doesn't support colored prompt? Try changing the prompt settings at
