Subject: sapply puzzlement
In-Reply-To: <87r5bx3ms2.fsf@gmail.com>
sapply(z, function(row) ...) does not actually grab a row at a time out of
'z'. It grabs a column (because 'z' is a data.frame)
You may want:
t(apply(z, 1, function(row) row - means))
or:
t(t(z) - means)
Hope that helps,
-David Johnston
