Dear John,

Thanks a lot for the time you spent on my problem. I don't believe you can do something to avoid this kind of problem.

I don't know if it is technically possible but I wonder if when we load Rcmdr plug-ins from the Rcmdr menu, it wouldn't be possible during the restart of Rmcdr to detach the package used by Rcmdr in order to load them after the packages used by the plug-ins in order to at least avoid to break Rmcdr (in breaking I mean to prevent from using Rcmdr functions like recode (from car) in my example).

Regards,
Alain
