failed to load MASS at start up
A belated follow-up on this -- I was on holiday over Easter.

Why would you want to do that? There are options to set the list of
default packages, and
options(defaultPackages=c(getOption("defaultPackages"), "MASS"))
in .Rprofile is the preferred way to do this (and it works).
R : Copyright 2003, The R Development Core Team Version 1.7.0 (2003-04-16) .... Type `q()' to quit R. Error in get(x, envir, mode, inherits) : variable "biplot" was not found Error in library(MASS) : package/namespace load failed [Previously saved workspace restored]
What's happening? I also tried to load 'lattice' (which I assume is where biplot is defined) before 'MASS', but got the same error.
biplot is in mva

By default mva is loaded but perhaps that does not occur until after ~/.Rprofile is executed.
That's true. Default packages are loaded right at the end of the startup options. To fix this you could add the following line to .../library/MASS/NAMESPACE importFrom(mva, biplot) Unfortunately, that would load *two* copies of mva if MASS is loaded before mva (as I understand it), which is why I removed it from the NAMESPACE file. I'll reinstate it for some future revision, possibly by a require(MASS) in a .onLoad.
