Generate N Uniform Random Points On Line Segments

Description

Given a line segment pattern, generate a random point pattern consisting of n points uniformly distributed on the line segments.

Usage

runifpointOnLines(n, L)

Arguments

n

Number of points to generate.

L

Line segment pattern (object of class "psp") on which the points should lie.
