spatial cross-correlation
Hi; I cannot find in the R html documentation a way to evaluate cross-correlation in 2D data sets. I would like to evaluate cross-correlation in a series of moving windows between two maps. i,e, specify several windows inside the complete 2D spatial matrixes and for each one ofthese windows evaluate the 2D cross-correlation (commonly conducted in the spectral domain). Thanks in advance and best

Both of these commands work fine outside the function, but I would like to wrap them in a function so I can apply the code iteratively to many such objects. Here's what I wrote, but it doesn't
