Past Meetup

apply() and relatives

This Meetup is past

11 people went


A discussion of apply, tapply, lapply, sapply, mapply, rapply, aggregate, by, split, rowSums, etc.

(and if time permits those distant relatives who should best be left locked in dusty attics: and reshape)

No add on packages here, just straight R (though I may show some timing comparisons for the fun of it).

A BIG thanks to John for stepping in at short notice.
