In a raster asc object, I'd like to take the positions (x and y coordinates)
for a given pixel ID. Any idea about how to do this?

Maybe a very basic question.
How can I get mean of a object like this
str(object)
num [1:53, 1:2] 734 734 736 734 736 ...
- attr(*, dimnames)=List of 2
..$ : NULL
..$ : chr [1:2] x y
I want the mean of both x and y

it with a single function?

useful replies from R users. Those two object both appear to be matrices and
both should be handled by those functions.

I hope this help to clarify the objects I'm getting with the loop.

So you need to show us how you made the second object. (The Posting Guide's
