max(bin).
bin.
nbins rows and the same number of columns as
bin.
The
[i,j] element of the value is
the number of
is that occured in
bin[,j].
The result is equivalent to
apply(bin, 2, tabulate, nbins=max(bin)),
except that column names are ignored.
Or, if
weights is supplied, the weights for observations with
bin[,j] == i.
