R-Help 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.
