and to really answer Chris' question:
The MASS source *is* of course inside the R-1.9.0.tgz that
Unfortunately (for a good reason, but still unfortunately!)
the recommended packages' sources (and MASS is one of those) are
*still* compressed even after unpacking R-1.9.0.tgz :
After unpacking R-1.9.0.tgz, to see the source, you need to
unpack (the symbolic link) VR.tgz as well :
and then VR/MASS/R/lda.R and (a small part of) VR/MASS/src/MASS.c
This is a bit unfortunate for those of us who like to search
inside the sources..
