Frank, The default is to exclude NA's based upon the argument 'na.last = NA'. If you set the argument 'na.last' to either TRUE or FALSE, the NA's will be kept and sorted either last or first respectively. > sort(c(3,1,NA), na.last = TRUE) [1] 1 3 NA > sort(c(3,1,NA), na.last = LAST) [1] NA 1 3 See ?sort HTH, Marc Schwartz ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
