R: Invoke Text Editor on Spatial Data

edit.ppp {spatstat} | R Documentation

## Invoke Text Editor on Spatial Data

### Description

Invokes a text editor allowing the user to inspect and change entries in a spatial dataset.

### Usage

    ## S3 method for class 'ppp'
    edit(name, ...)

    ## S3 method for class 'psp'
    edit(name, ...)

    ## S3 method for class 'im'
    edit(name, ...)

### Arguments

`name` | A spatial dataset (object of class `"ppp"`, `"psp"` or `"im"`).
`...` | Other arguments passed to `edit.data.frame`.

### Details

The function `edit` is generic. These functions are methods for spatial objects of class `"ppp"`, `"psp"` and `"im"`.

The spatial dataset `name` is converted to a data frame or array, and the text editor is invoked. The user can change the values of spatial coordinates or marks of the points in a point pattern, or the coordinates or marks of the segments in a segment pattern, or the pixel values in an image. The names of the columns of marks can also be edited.

If `name` is a pixel image, it is converted to a matrix and displayed in the same spatial orientation as if the image had been plotted.

Note that the original object `name` is not changed; the function returns the edited dataset.

### Value

Object of the same kind as `name` containing the edited data.
