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.
