Subject: [R] Constructing a matrix of outputs from loop

R -

I would like to construct a matrix from the output of a loop that
has 2
values it varies over the course of the loop creating a 20x20 matrix
of
output values:

 ap = logspace(-3, 0, 20)

 am = logspace(-3, .7, 20)
  for (ap in apList)
  {
   for (am in amList)
   {

 output = func(ap, am)
}
}

i.e. cell 1x1 is -3,-3 and the value is 45 or something
