I believe that should be read as "unable to allocate contiguous block of memory for a new object of size 2Gb". The general rule is that you should have at least 3 times the free (non-OS/non-other-running-applications) RAM as the size of your largest objects. You seem to be in violation of that rule. -- David Winsemius Alameda, CA, USA ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
