[R] Help with tables in R

[PIKAL Petr]

Hi

Hm. Cooperation of R with excel can be probably done by Rexcel package.

Without more detailed information how do you want to use R in connection with Excel you probably do not get more precise answer.

For summaries use
?aggregate or maybe ?sapply

For counting item occurance
?table, ?xtabs or sum(something == "something")

can be used.

Regards
Petr
