methods.layered: Methods for Layered Objects

Description

Methods for geometrical transformations of layered objects (class "layered").

Usage

## S3 method for class 'layered':
shift(X, ...)
  ## S3 method for class 'layered':
rotate(X, ...)
  ## S3 method for class 'layered':
affine(X, ...)
  ## S3 method for class 'layered':
reflect(X)
  ## S3 method for class 'layered':
flipxy(X)
  ## S3 method for class 'layered':
rescale(X, s)
  ## S3 method for class 'layered':
scalardilate(X, ...)

Arguments

X

Object of class "layered".

...

Arguments passed to the relevant methods when applying the operation to each layer of X.

s

Rescaling factor passed to the relevant method for rescale. May be missing.

Value

• Another object of class "layered".

Details

These are methods for the generic functions shift, rotate, reflect, affine, rescale, scalardilate and flipxy for the class of layered objects.

A layered object represents data that should be plotted in successive layers, for example, a background and a foreground. See layered.

Examples

L <- layered(letterR, runifpoint(20, letterR))
  plot(L)
  plot(rotate(L, pi/4))
