Creating a moving window average with two distance matrices

I wrote a short function in R that combines two distance matrices (for example a floristic dissimilarity matrix and a geographical distance matrix).

The function takes the elements from the first matrix and averages all the distances according to either:

• a number of neighbouring cells

• an absolute distance between neighbouring cells

The result is a vector of averaged values. This can then be visualized to see how dissimilarity changes with spatial scales.
