I'm not sure if this is correct behavior or not, but it seems counterintuitive to me:
dat <- data.frame(id=1:5, let=letters[1:5]) # A. omits the first row dat[- 1, ] # B. unexpectedly omits ALL rows dat[- integer(0), ] It would be less surprising if there were no rows omitted in the (B) case. ______________________________________________ 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.
