as.data.frame.ppp {spatstat.geom} | R Documentation

## Coerce Point Pattern to a Data Frame

### Description

Extracts the coordinates of the points in a point pattern, and their marks if any, and returns them in a data frame.

### Usage

    ## S3 method for class 'ppp'
    as.data.frame(x, row.names = NULL, ...)

### Arguments

`x` | Point pattern (object of class `"ppp"`).
`row.names` | Optional character vector of row names.
`...` | Ignored.

### Details

This is a method for the generic function `as.data.frame` for the class `"ppp"` of point patterns.

It extracts the coordinates of the points in the point pattern, and returns them as columns named `x` and `y` in a data frame. If the points were marked, the marks are returned as a column named `marks` with the same type as in the point pattern dataset.

### Value

A data frame.
