Thanks for pointing out TraMineR; it is a very interesting package on sequences of events and states in social science. Unfortunately, it appears not provide the kind of windowing or counting of subsequences that I was asking for. Therefore, I am still looking for implementations of procedures for event sequence analysis as provided in some data mining tools and applications, see for example the article cited below. Any help would be very much appreciated. Thanks, Hans Werner Borchers ------------ Le 2 févr. 09 à 13:31, Hans W. Borchers a écrit : Dear R help, I am analyzing sequences of events described by time and a unique event tag. And I am searching for recurring patterns where patterns have to show up in a certain time window, e.g. 5 or 10 minutes. Of course, inbetween these events other events may occur. I have applied basket analysis approaches like apriori or 'frequent item set' algorithms with interesting results but these methods do not take into account the exact succession of events. I also looked into the 'Generalized Sequential Pattern' function of Weka, but the implementation in Weka does not allow for a time window (as far as I understand). Are there other sequence analysis implementations available in R? -- For instance in the realm of the 1997 paper "Discovery of frequent episodes in event sequences" by H. Mannila et al. Please no BioConductor hints as they are meaning something different with (genetic) sequence analysis.
