Hi, I had an example like this: id user action 1 12 login 2 12 view 3 12 view 4 12 view 5 12 login 6 12 view 7 12 view 8 12 login which I used to split using split(dat1,cumsum(dat1$action=="login")).
If I had a similar example: id user IP 1 12 ip1 2 12 ip1 3 12 ip2 4 12 ip2 5 12 ip2 6 12 ip3 7 12 ip3 8 12 ip3 how can I split data frame to obtain the following structure: #1 1 12 ip1 2 12 ip1 #2 3 12 ip2 4 12 ip2 5 12 ip2 #3 6 12 ip3 7 12 ip3 8 12 ip3 thanks, Srecko [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
