[R] novice questions

[Bert Gunter]

Your English isn't the problem. It's your failure to do your homework
first: Please read "An Introduction to R," the tutorial that ships
with R, or one of the many tutorials on the web (including in your
native language, very likely), so search. Here also is another
possible resource:
http://cran.r-project.org/other-docs.html

Cheers,
Bert
