[R] identify object that causes "Error in loadNamespace(name) : there is no package called ‘R.utils’"

[Liviu Andronic]

Dear all,
I've bumped into the: "Error in loadNamespace(name) : there is no
package called ‘R.utils’" error. I've already read a bit on this (
http://www.cybaea.net/Blogs/Data/A-warning-on-the-R-save-format.html )
but I have a follow-up question.

Given a workspace that automatically loads a package that I don't
really need/want (e.g. ‘R.utils’), how do I identify which object
requires this package to load? I would like to avoid loading ‘R.utils’
every time I open an R session.

Regards,
Liviu
