This looks like a problem I had too and, although I don't know for sure, concluded it was due to an error in the path that R uses to find a required library or part of a library. I solved it by installing a local version of R in my home directory and using that instead of the central installation. That seemed to overcome the inconsistency producing the error.

perhaps some of the R wizards on this list can help me with the following error. I connect to corn via ssh -X, I start R in command line, then try to do a very simple linear regression using lm(). However it seems that the R installation on farmshare is broken? It seems not to find, which lm needs to perform a Cholesky inversion! Anyone knows why that is the case ? I attach a code snippet below.
