Hello Alok,
We really need more details about what you are trying to acheive in order to
help you.
c(X, Y) concatenates the objects X and Y. The result will be a vector. If X
and Y happen to be m x n matrices, the result will be a vector of length 2 *
m * n: probably not what you want.
You can

I want to do what the examples in Spatstat do with regard to the point
and pixel/image data bei and bei.extra.. (bei.extra contains a list of
two image files --elevation and gradient. They plot these two items
(and also take log, I believe)
In my case:

Hi:
Let me start by saying that I am new to R. I converted two pixel ascii
matrices into image files:
X_im - im(X) # X is an ascii pixel matrix
Y_im - im(Y) # Y is an ascii pixel matrix
How can I combine these two images into 1) one datafile XY_im, 2) save
it and 3) read it after
