[Rd] Compiling R with ATLAS

[Douglas Bates]

There is a Debian/Ubuntu specific list, R-SIG-Debian at R-project.org,
which I am cc:'ing on this reply, that is a better location for this
discussion.

It appears that you may be going about things the hard way.  There are
Ubuntu packages for atlas and for R that can handle all of this for
you.  Take a look at http://cran.r-project.org/bin/linux/ubuntu for
information on how to get started.  It will probably be much easier to
install the pre-compiled packages first and worry about compilation
for customization later.
