Harold,

Try looking in C:\Program Files\R\rw2001\library (presuming the default
install path) to see if the MASS folder is still there. If it is, then what
exactly is the error message you are getting when you try library(MASS)?

If MASS is no longer there, I would try the Packages > Install Packages from
CRAN.. menu item in the R Console and see if VR is listed. If so, install
that by the Select > OK process and MASS should be restored.  Actually, this
*might* work even if you still have a MASS folder.

Hope that helps,
Bill
