The documentation says, "pmax and pmin take several vectors as
arguments and return a single vector giving the parallel maxima
(or minima) of the vectors."

I discovered that, if you use a matrix or array instead of a
vector, pmax returns a matrix or array, respectively.

This makes pmax and pmin much more useful, and should not be left
to people to discover on their own!

For example:
m1 <- array(1:24,c(2,3,4))
m2 <- array(24:1,c(2,3,4))
