Right (or use an environment variable). ?options tells us:
the packages that are attached by default when R starts up. Initially
set from value of the environment variables R_DefaultPackages, or if
that is unset to c("methods", "ctest"). (Set R_DEFAULT_PACKAGES to NULL
or a comma-separated list of package names.) A call to options should be
in your `.Rprofile' file to ensure that the change takes effect before
the base package is initialized (see Startup)."
But the user's .Rprofile might be more appropriate for students who
don't have access to R's /etc directory likes in our department's
BTW: Is ?options completely correct?
I have  "ts" "nls" "modreg" "mva" "ctest" "methods"
in my list of defaultPackages, not only "methods" and "ctest". Looks
like an update is required. (talking about R-1.7.1 unpatched)
