R help - May 2009 - Finding Longest Identical Subsequence across Multiple Time Series?

Hi all

Does anyone here know of an efficient algorithm to find the longest
identical subsequence across multiple time series? Say I have two time
series A and B (not necessarily of identical length), and I wish to find the
beginning and ending index of the longest common subsequence across both
series. Is there an efficient way to do this , or a package which will do
what I want?

Cheers
