This function computes an estimate of the cross K-function using the translation invariant edge correction (Ohser, 1983). The procedure only works for point patterns observed within a rectangular observation window.
A list with three components t, Kij, and Kji where t is the
distances for which the cross K-function is estimated and
Kij and Kji are the cross K-function estimates (these
are equal with the edge correction used, see details).
