In spatstat.geom: Geometrical Functionality of the 'spatstat' Family

Extract or Change the Containing Rectangle of a Spatial Object

Description

Given a spatial object (such as a point pattern or pixel image) in two dimensions, these functions extract or change the containing rectangle inside which the object is defined.

Usage

   Frame(X)

   ## Default S3 method:
Frame(X)

   Frame(X) <- value

   ## S3 replacement method for class 'owin'
Frame(X) <- value

   ## S3 replacement method for class 'ppp'
Frame(X) <- value

   ## S3 replacement method for class 'im'
Frame(X) <- value

   ## Default S3 replacement method:
Frame(X) <- value

Arguments

X	A spatial object such as a point pattern, line segment pattern or pixel image.
value	A rectangular window (object of class "owin" of type "rectangle") to be used as the new containing rectangle for X.

Details

The functions Frame and Frame<- are generic.

Frame(X) extracts the rectangle inside which X is defined.

Frame(X) <- R changes the rectangle inside which X is defined to the new rectangle R.

Value

The result of Frame is a rectangular window (object of class "owin" of type "rectangle").

The result of Frame<- is the updated object X, of the same class as X.
