Well, given that delta is an unspecified argument and that its default, which the poster might have looked up, is diff(range(x)), the poster might have suspected that perhaps the range of x, i.e. data$V1, is either 0 or non-finite. In the former case, all values of x are identical, in the latter, there are Inf or NA values among them. Either way, summary(data$V1) should be enlightening. >> >> Many thanks! >> >> [[alternative HTML version deleted]] >> >> ______________________________________________ >> 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. > > Don McKenzie > Research Ecologist > Pacific Wildland Fire Sciences Lab > US Forest Service > > Affiliate Faculty > School of Environmental and Forest Sciences > University of Washington > d...@uw.edu > > ______________________________________________ > 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. -- Peter Dalgaard, Professor, Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark 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.
