[Rd] Cannot Restore Workspace with R 1.9.1 (PR#7012)

This has recently been discussed in R-help with several workarounds. See
and the rest of the thread.

Yet another workaround is

R --vanilla
> load(".RData")

It is not a bug in R, and it is not new in 1.9.1 (the person who reported
problems was using prior to release of 1.9.1).  A more permanent
workaround will appear in the next update of the VR bundle.  AFAICS the
problem reported by Roland Reis is actually in nlme, which manages to
require MASS, grid, lattice and nlme namespaces to reload a glmmPQL object
(via the environment of some embedded formula).

Please don't use R-bugs to ask questions -- see the R FAQ and the posting
guide for the correct places.

Yes. See the R-help archives.
