[R] Matrix langage

[Pierre-Olivier Chasset]

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
