Thanks a lot to all of you! Now I see, that use of R (and S) is very different from use of Matlab. There is no one-to-one correspondence. I'm shy to ask so stupid questions, but name of language R makes it hard to find relevant links trough google. Thanks for pointing to "S Poetry", I would never find it alone, since I was looking for R-related info.
Thanks, Daniil.
