I have a need to find aggregated patterns within a data.frame of some 80
million records and wanted to know if there are any packages which could be
used to find patterns by row. For example
Col 1 Col 2 Col3
A 1 aa
A 2 bb
A 1 aa
In this example pattern A - 1 - aa occurs twice, and A - 2 - bb occurs once.
Presently I'm simply concatenating the columns and performing a group by,
and count. Which works but wonder if there were any packages that would
perform such (and maybe other) analytics.
