playwith (version 0.9-11)

playDev: Work with the playwith device

Description

Part of the playwith Application Programming Interface.

Usage

playDevCur()
playDevList()
playDevSet(playState)
playDevOff(playState = playDevCur())

Arguments

playState

a playState object representing the plot, window and device.

Value

• playDevCur returns the currently active playState object. playDevList returns a list of playState objects for all open playwith plot windows.

Details

These are analogous to dev.cur, dev.list, dev.set and dev.off, and do in fact call these lower-level functions. Specifically, it is recommended to call playDevSet(playState) before any direct drawing operations, to ensure that this is the current graphics device.
