khvc

Calculate the covariance matrix for the difference between two K-functions.
Also return the contribution to the variance for each of the two point
patterns,

The Splancs package was written as an enhancement to S-Plus for display and analysis of spatial point pattern data; it has been ported to R and is in "maintenance mode".
