[R] Problem with the recode function

[Alain Guillet]

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
