NA or work around ??
...(na.action. and other things), but I
can't see
to figure this out.
I'm guessing this is so simple I'll feel foolish for asking, but here goes.
Thanks,

by function ??
I'm just learning and this is probably very simple, but I'm stuck.
I'm trying to understand the by().
This works.
by(TestData, LEAID, summary)
But, This doesn't.
by(TestData, LEAID, median(RATIO))
ERROR: could not find function "FUN"
HELP!
Thanks,
LA
