I can do that for workstations which I have admin priviledges and have a private version of R; how about the ones I don't? > R 2.1.0 will provide a portable way of overriding the configured > "site" compilation flags via user-level ~/.R/Makevars files.

And how will it handle the situation where one's home directory is NFS mounted across several architectures? There will be a variable to override the default location, right?. ---------------------------------------------------------- SIGSIG -- signature too long (core dumped) ______________________________________________ R-devel@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
