Is the Current Graphics Device Interactive?

Test if the current graphics device (or that which would be opened) is interactive.

Keywords: device

Usage

dev.interactive(orNone = FALSE)
deviceIsInteractive(name = NULL)

Arguments

orNone: logical; if TRUE, the function also returns TRUE when .Device == "null device" and getOption("device") is among the known interactive devices.
name: one or more device names as a character vector, or NULL to give the existing list.

Details

The X11 (Unix), windows (Windows) and quartz (OS X, on-screen types only) are regarded as interactive, together with JavaGD (from the package of the same name) and CairoWin and CairoX11 (from package Cairo). Packages can add their devices to the list by calling deviceIsInteractive.

Value

dev.interactive() returns a logical, TRUE if and only if an interactive (screen) device is in use.
deviceIsInteractive returns the updated list of known interactive devices, invisibly unless name = NULL.

Examples

library(grDevices)

dev.interactive()
print(deviceIsInteractive(NULL))
