Distance Map of Point Pattern on Linear Network
Description
Computes the distance from each pixel to the nearest point in the given point pattern on a linear network.
Usage
## S3 method for class 'lpp'
distmap(X, ..., k=1)
Arguments

Details
This is a method for the generic function distmap.
It computes the distance map of the point pattern X
as a pixel image on the network.
At a pixel u, the greyscale value
equals the distance from u to the
nearest point of the pattern X (or the k-th nearest point
of X).
Value
A pixel image on the network (object of class "linim")
whose greyscale values are the values of the distance map.
