does it ever fail if you try the example in a fresh r session (i.e., one without anything executed before this code)? when it fails, what is t? have you redefined t to be some other function, in particular, a no-argument one, as here: t = function() NULL a = matrix(1:30, 5, 6) t(a) # Error in t(a) : unused argument(s) (1:30) this is most likely what happens here. vQ ______________________________________________ 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.
