Re: [R] Problem with na.omit when using length()

Thanks for that. It works as expected now. A case of GIGO (garbage in- garbage out) on my part, with some head-banging. :-) Regards Viju Moses Yihui Xie wrote: just put na.omit() inside length() if you intend to omit the NA elements of the vector (otherwise you are trying to omit the NA's of t
