    I have some functions that currently operate on a vector of data.
    I would like to convert these to moving window functions.

    eg.
    Like sum that adds the total value of a vector.
    and msum that gives the sum within a moving window.

    I would like to be able to take a function f[v]. and do window[f;window;v] to have that function applied over moving windows of v.

    Am I clear in my explanation?
    and can anyone suggest the best way to do this?
