It does work. That's a warning, not an error. If you want to know why the warning is there, it's because the code turns a 37-element vector into a 12x3 matrix. This drops the last element. In S-PLUS, and in some older versions of R, there is no warning, but in current R there is a warning. The answer is the same, though. -thomas ______________________________________________ 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
