Thanks for everyones help - mydat was not what I thought it was. str(mydat) showed: $ Date : Factor w/ 1504 levels "","2002-11-22",..: 295 295 295 295 295 295 295 295 295 295 ... $ Time : Factor w/ 72447 levels "","00:00:00",..: 15423 15470 15509 17112 17136 17159 17209 17239 17266 21527 ... I didn't properly convert date and time using chron. Not sure how R plots factor levels, but obviously it has problems with it!

That shouldn't by itself cause concern. It is always the _last_ allocation that triggers the message, so it could happen due to allocation of 3 vectors of size 800M. Straw, camel, back... Another matter is that memory.size is the amount _used_, not amount _available_, so you would seem to have more like 1500M left. However, it does look odd that mydat with dimensions 245x9 should generate an 800M memory request. As others have suggested, perhaps mydat is not what you think it should be... -- Peter Dalgaard Center for Statistics, Copenhagen Business School Phone: (+45)38153501 Email: pd....@cbs.dk Priv: pda...@gmail.com ______________________________________________ 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.
