Hi, I'm playing with data.table package and I need some help to better understand it.
I've posted an answer related to it (and related to join table and aggregate results data) here <http://stackoverflow.com/questions/13571359/join-and-sum-not-compatible-matrices-through-data-table> (Join and sum not compatible matrices through data.table on stackoverflow). If someone here can share its knowledge :) Thanks in advance.
