height:

Object of class "numeric". A vector of length one representing the height of the rectangle.

Extends

Class PictureContent, directly.

Methods

applyTransform

signature(object = "PictureRect", tm = "matrix"): transforms the locations described by the rectangle object by a 3x3 transformation matrix and returns a "PictureRect" object with the transformed locations.

grobify

signature(object = "PictureRect"): converts the object into a grid rectangle grob.

While not intended to be used directly, this method contains three arguments:

defs

An object of class "PictureDefinitions" that contains definitions of graphical content, primarily for use with the gridSVG package.

gpFUN

This argument takes a function that should expect to take a single gpar object and return a modified gpar object. By default, the value of this argument is the identity function.

ext

A character vector. See grid.picture for more information on what this extension selection parameter means, in addition to the valid values this argument takes.
