dev.size Find Size of Device Surface Find the dimensions of the device surface of the current device.
dev.size(units = c("in", "cm", "px"))
units | the units in which to return the value – inches, cm, or pixels (device units). |
A two-element numeric vector giving width and height of the current device; a new device is opened if there is none, similarly to dev.new().
The size information in inches can be obtained by par("din"), but this provides a way to access it independent of the graphics sub-system in use. Note that par("din") is only updated when a new plot is started, whereas dev.size tracks the size as an on-screen device is resized.
dev.size("cm")
