R help - Jul 2011 - simulation for equation with two variables

Hi,
I'm trying to run a basic simulation and sensitivity test by running an
equation with two variables and then plotting the results against each of
the vectors. R is running the vectors like this : 0 with 0, 1 with 1, etc. I
would like it to run them like 0 for 1:100, 1 for 1:100, and then the
reverse (so 100^2*100@ iterations. How do I get it to do that? Here's what I
have so far:

par(mfrow=c(1,2))
 t <- 0:100
 DBH <- 0:100
 M <- 4000*(1-exp(-t*(1.104-(0.67*0.7)-0.163*log(DBH))^2)))
 plot(M~DBH)
 plot(M~t)

That is, run all possible combinations of the two vectors through the
equation.
