[R] R-update - what about packages and ESS?

[Richard M. Heiberger]

ESS finds R by one of two mechanisms.

If R is in your PATH, then ESS will find it.

Or, if you have explicitly set the emacs variable
inferior-R-program-name, in .emacs, site-start.el, or ess-site.el,
then ESS will find R.

My guess is that you have explicitly set inferior-R-program-name
to your previous version of R.
