Well
- MASS is a package and not a library
- it is not 'base' but 'contributed', and as library(help=MASS) says,
support software for a book. It is on CRAN.

Hello everyone,
Can anyone tell me how do I restore data in a data.frame provided by base
R libraries (MASS) ?
I uninstalled R then installed it again and I still see the new changes I
made!!!???
(eg. whiteside$Temp=1 ==> 1 overwrote all the rows, I want the old values :(
!!
Please HELP!
