Usage
# S3 method for ppp
summary(object, …, checkdup=TRUE)
Arguments
object

Point pattern (object of class "ppp").

Ignored.

checkdup

Logical value indicating whether to check for the presence of duplicate points.

Details

A useful summary of the point pattern object is printed.

This is a method for the generic function summary.

If checkdup=TRUE, the pattern will be checked for the presence of duplicate points, using duplicated.ppp. This can be time-consuming if the pattern contains many points, so the checking can be disabled by setting checkdup=FALSE.

If the point pattern was generated by simulation using rmh, the parameters of the algorithm are printed.
