That FAQ does not provide any examples of the A[B] syntax used with data table objects. It does provide an example using A[B] with matrix objects, but the example does not translate to data table objects, so I'm not sure why it's there. I suggest that the FAQ be extended to provide one, or better yet several, examples of the A[B] syntax applied to data.table objects.
As far as I have been able to puzzle out so far, A[B] is just another way to do a merge. -- View this message in context: http://r.789695.n4.nabble.com/A-B-tp4689942p4690040.html Sent from the datatable-help mailing list archive at Nabble.com. _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
