Are least-squares means useful or appropriate?

Hi.
My question was just theoric. I was wondering if someone who were using
SAS and R could give me their opinion on the topic. I was trying to use
least-squares means for comparison in R, but then I found some
indications against them, and I wanted to know if they had good basis
(as I told earlier, they were not much detailed).
Greetings.

|       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.
