[R] update MASS

[Ramón Casero Cañas]

I'd like to update MASS from version 7.2-11 to version 7-2.19. I am
running R 2.0.1 on ubuntu, that installs MASS with the package r-cran-vr.

I have tried doing update.packages(), and I get a list of packages that
I could update, but none is called MASS.

I have tried the following too, right after launching emacs, but to no
avail.

</QUOTE>


I have the package installed in /usr/lib/R/library/MASS. I can do

<QUOTE>
> library(MASS)
> search()
 [1] ".GlobalEnv"        "package:MASS"      "package:methods"
 [4] "package:stats"     "package:graphics"  "package:grDevices"
 [7] "package:utils"     "package:datasets"  "Autoloads"
[10] "package:base"
</QUOTE>


How could I update the package?

Thanks,
