I suggest using NULL for arguments which are vectors or lists of unspecified length, and NA for "scalars" (arguments whose length should always be one, such as na.rm). I rarely use missing arguments, as they are harder to pass down to other functions. -- David Brahm ([EMAIL PROTECTED]) ______________________________________________ R-help@stat.math.ethz.ch 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.
