Subject: mean of 3D arrays
Hi,
I have multiple three dimensional arrays.
Like this:
x1 <- array(rnorm(1000, 1, 2), dim=c(10, 10, 10))
x2 <- array(rnorm(1000, 1, 2), dim=c(10, 10, 10))
x3 <- array(rnorm(1000, 1, 2), dim=c(10, 10, 10))
Now I would like to compute the mean for each corresponding cell.
As a result I want to get one 3D array (10 x 10 x 10) in which at position x, y, z is the mean of the corresponding values of x1, x2 and x3 (at position x, y, z).
How can I do this?
