See ?Startup or the appropriate appendix to `An Introduction to R'.

Comment to Uwe: it is _not_ a good idea to tamper with .../etc/Rprofile,
as that is part of base (and base is now a namespace).  Use
.../etc/Profile.site or .Rprofile instead, each of which is sourced in the
user workspace.

Probably the best idea is to have a file .Rprofile containing the single
line

library(quantreg)

in the same directory as the R scripts you want to run. Then every time
you start Rterm _in that directory_, that .Rprofile will be run.

Note: for Classic MacOS users, there is no Rprofile.site despite what
?Startup says in R <= 1.6.0, so use the appendix to `An Introduction to
R'.


[I have proposed a simpler mechanism for this along the lines of S4's,
with a set of files like .Rpackages and Rpackages.site which contain a
list of packages to be loaded.  It's likely to get implemented for 1.7.0.]
