R: Summary of a Point Pattern Dataset

summary.ppp {spatstat.geom} | R Documentation

## 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 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.

### Examples

      summary(cells)  # plain vanilla point pattern

      # multitype point pattern
      woods <- lansing

      summary(woods) # tabulates frequencies of each mark

      # numeric marks
      trees <- longleaf

      summary(trees) # prints summary.default(marks(trees))

      # weird polygonal window
      summary(demopat)  # describes it
