[R] error open .RData

[Horacio Montenegro]

     hi

     It seems that, in some cases, saving a .RData
containing objects from some packages and later trying
to start R (or load the .RData) before loading the
package could cause this error. See

http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46910.html

     If the .RData contains objects from some specific
packages, try loading the package first and then load
the .RData file.

     Also, RSiteSearch(".RData corrupted") results in
lots of hits.

     hope this helps,
