Function spatstat.geom::psp() creates a line-segment-pattern (psp.object), i.e., an R object of S3 class 'psp'.

The S3 generic function spatstat.geom::as.psp() converts R objects of various classes into a line-segment-pattern. Listing 38.1 summarizes the S3 methods for the generic function as.psp() in the spatstat.* family of packages,
