Generates \(n\) independent random points on a linear network with a specified probability density.
rlpp(n, f, ..., nsim=1, drop=TRUE)If nsim = 1 and drop=TRUE,
a point pattern on the linear network,
i.e.\ an object of class "lpp".
Otherwise, a list of such point patterns.
Number of random points to generate. A nonnegative integer giving the number of points, or an integer vector giving the numbers of points of each type.
Probability density (not necessarily normalised).
A pixel image on a linear network (object of class "linim")
or a function on a linear network (object of class "linfun").
Alternatively, f can be a list of functions or pixel images,
giving the densities of points of each type.
Additional arguments passed to f if it is a function
or a list of functions.
Number of simulated realisations to generate.
Logical value indicating what to do when nsim=1.
If drop=TRUE (the default), the result is a point pattern.
If drop=FALSE, the result is a list with one entry which is a
point pattern.

The linear network L, on which the points will be generated,
is determined by the argument f.
If f is a function, it is converted to a pixel image
on the linear network, using any additional function arguments
....
If n is a single integer and f is a function or pixel image,
then independent random points are generated on L with
probability density proportional to f.
If n is an integer vector and f is a list of functions
or pixel images, where n and f have the same length,
then independent random points of several types are generated on
L, with n[i] points of type i having probability
density proportional to f[[i]].
