Thanks to user dnlbrky, we now have a third way to accomplish sessionizing log data for any arbitrary time out period (see methods 1 and 2), this time using data.table from R along with magrittr for piping:

I agree with dnlbrky in that this feels a little better than the dplyr method for heavy SQL users like me, but ultimately, I still think the SQL method is the most elegant and obvious to understand. But that’s the great thing with open-source software; pick any tool you want, accomplish whatever you choose using any method you choose.
