If you are interested in extracting seasonal patterns from time
series, you might wish to check out ?stl (in the stats package). Of
course, there are all sorts of ways in many packages to fit
seasonality in time series that are more sophisticated, but probably
also more complicated, than your manual summarization and plotting.
