Yes, ``The way'' for base installation and re-installation is

	make
	----

This is from the R-FAQ:

     In R, the startup mechanism is as follows.  R first searches for the
     site-wide startup profile unless the command line option
     `--no-site-file' was given.  The name of this file is taken from the
     value of the `RPROFILE' environment variable.  If that variable is
     unset, the default is ``$RHOME'/etc/Rprofile'.  Then, unless
     `--no-init-file' was given, R searches for a file called `.Rprofile'
     in the current directory or in the user's home directory (in that
     order) and sources it.  It also loads a saved image from `.RData' in
     case there is one (unless `--no-restore' was specified).  If needed,
     the functions `.First()' and `.Last()' should be defined in the
     appropriate startup profiles.

I.e., if you want a ``global Rprofile'', then use the RPROFILE variable:

	RPROFILE=/u/jl/R/Rprofile export RPROFILE	 (..sh)
or
	setenv RPROFILE /u/jl/R/Rprofile		 (..csh)

You are right.  Fritz ?

Fritz has already answered this:  Use
	make R ; make help
