[R] Matrix langage

[Doran, Harold]

All of this is possible, and very easy, in R. See the Intro to R book.
Doug Bates also has an article in the recent edition of R News showing
how to perform matrix operations for least squares.

Subject: [R] Matrix langage

Hello,

I would like to use R in a laboratory. They use actually IML of the
SAS-Society. With this IMLangage, you can enter a mathematical formula
with sum from i to n, transpose matrix, sum of a colonne and all this
stuff. After that, the software can translate it in a program.
I am not currently use R in Matrix langage. But I manipulate data frame.

I have the feeling that R can do like SAS do.
What do you think about it?
Thanks in advance,

Pierre-Olivier Chasset
