Posted code needs to be self contained and reproducible so that others can copy it from your post, paste it into R and see the same problem you are seeing.

If by "calling" the time is intended to refer to "extracting" the time then time(x) gives a vector of times. -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at 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.
