Summary of a Point Pattern Dataset

Description

Prints a useful summary of a point pattern dataset.

Usage

 ## S3 method for class '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 dublicate 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.
