Random Perturbation of a Point Pattern on a Network
Applies independent random displacements to each point in a point pattern on a network.
rjitterlpp(X, radius, ..., nsim = 1, drop = TRUE)
X |
A point pattern on a linear network
(object of class |
radius |
Scale of perturbations. A positive numerical value. Each point will be displaced by a random distance, with maximum displacement equal to this value. |
... |
Ignored. |
nsim |
Number of simulated realisations to be generated. |
drop |
Logical. If |
Each of the points in X will be displaced along the network
by a random amount, independently of other points.
The maximum displacement distance is specified by radius.
Each point remains on the same line segment of the network
as it originally was.
