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.
Very best, Hans Werner
