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

| dev.size("cm") |
