Estimado Felipe:

	  If you provide a very simple example (as suggested in the posting 
guide, www.R-project.org/posting-guide.html), it would allow those of 
use who rarely use SAS to respond.  Try to think of the simplest 
possible toy data set and analysis that shows the difference between the 
SAS answer and the answer you get from a certain R function.  If you 
post something simple of that nature that someone can copy from your 
email into R and try other things in a minute or two, it will likely 
increase the speed and utility of a reply.

	  Buena Suerte,
