recordPlot: Record and Replay Plots

Description

Functions to save the current plot in an R variable, and to replay it.

Usage

recordPlot()
replayPlot(x)

Arguments

x

A saved plot.

Value

recordPlot returns an object of class "recordedplot".replayPlot has no return value.

Warning

The format of recorded plots may change between R versions. Recorded plots can not be used as a permanent storage format for R plots. There were extensive changes in R 3.0.0, and now only plots from the current session can be replayed.

Details

These functions record and replay the displaylist of the current graphics device. The returned object is of class "recordedplot", and replayPlot acts as a print method for that class.

The returned object is stored as a pairlist, but the usual methods for examining R objects such as deparse and str are liable to mislead.

The displaylist can be turned on and off using dev.control. Initially recording is on for screen devices, and off for print devices.
