methods.layered: Methods for Layered Objects

Description

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

Usage

# S3 method for layered
c(...)
  # S3 method for layered
shift(X, vec=c(0,0), ...)
  # S3 method for layered
rotate(X, ..., centre=NULL)
  # S3 method for layered
affine(X, ...)
  # S3 method for layered
reflect(X)
  # S3 method for layered
flipxy(X)
  # S3 method for layered
rescale(X, s, unitname)
  # S3 method for layered
scalardilate(X, ...)

Value

Another object of class "layered".

Details

These are methods for the generic functions c, 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.

The method for c can be used to concatenate two or more layered objects ... into a single layered object, retaining the plot arguments.

The other methods apply geometrical operations to each of the layers of the layered object X.

Examples

  B <- owin(c(5500, 9000), c(2500, 7400))
  L <- layered(Window(demopat), unmark(demopat)[B])
  plot(L)
  plot(rotate(L, pi/4))
