Average K-functions from Simulations

Description:

     Forms the average of a series of (usually simulated) K-functions.

Usage:

     Kaver(fs, nsim, ...)

Arguments:

      fs: full scale for K-fn 

    nsim: number of simulations 

     ...: arguments to simulate one point process object 

Value:

     list with components 'x' and 'y' of the average K-fn on L-scale.
