R help - May 2003 - Error in library(MASS) : package/namespace load failed

Dear all,

I have installed 1.7.0 on my Win XP and want to use MASS. But I get this
error message:
> library(MASS)
Error in namespaceExport(ns, exports) : undefined exports: abbey,
accdeaths, Aids2, Animals, anorexia, austres, bacteria, beav1, beav2,
biopsy, birthwt, ...
Error in library(MASS) : package/namespace load failed

I therefore again downloaded VR.zip. When I extracted the files I always
answered yes to the question of "Would you like to replace the existing
file?"

I also "Skip File" MASS.dll because password is needed....?

I've never had this probelm with previous R versions and there is no
problem with other libraries. What have I done wrong?


Thanks in advance for your help!

Sincerely,
Tord

Had you done that before?  You didn't say so, but that would explain the 
symptoms.

*No* VR.zip is available for use with R 1.7.0: did you read the ReadMe in 
wherever you downloaded it from: it probably said `for rw1060/1/2 only'?

Most recently, installed a version of R 1.6.x on top of one for 1.7.0.
I suspect you've never done that before.

All I can suggest is that uninstall rw1070, remove all traces of the 
damage you have done, and try re-installing.
