I could not find `group-by` using the Browser. Grepping the source tree, it turned up in `grouping.extras`. > USE: math.statistics > [ id>> ] collect-by [ nip first ] { } assoc>map `collect-by` is a useful thing, got to keep it in mind.

I'm regularly rereading the documentation for `sequences` and `sets`, so maybe a little pointer to adjacent vocabs (at least *.extras) could be made. ---=====--- Александр ------------------------------------------------------------------------------ _______________________________________________ Factor-talk mailing list Factor-talk@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/factor-talk
