It is entirely independent, and R resolves what it loads via .libPath().

It's all documented and has been answered before, eg http://stackoverflow.com/questions/2170043/r-apt-get-install-r-cran-foo-vs-install-packagesfoo Dirk -- R/Finance 2012 Conference on May 11 and 12, 2012 at UIC in Chicago, IL See agenda, registration details and more at http://www.RinFinance.com _______________________________________________ R-SIG-Debian mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-debian
