runifpointOnLines {spatstat} | R Documentation |
Given a line segment pattern, generate a random point pattern
consisting of n
points uniformly distributed on the
line segments.
runifpointOnLines(n, L)
n |
Number of points to generate. |
L |
Line segment pattern (object of class |
This command generates a point pattern consisting of n
independent random points, each point uniformly distributed on
the line segment pattern. This means that, for each random point,
the probability of falling on a particular segment is proportional to the length of the segment; and
given that the point falls on a particular segment, it has uniform probability density along that segment.
A point pattern (object of class "ppp"
) with the same
window as L
