| quartz {grDevices} | R Documentation |
quartz starts a graphics device driver for the MacOS X System.
This can only be done on machines that run MacOS X.
quartz(display = "", width = 5, height = 5, pointsize = 12,
family = "Helvetica", antialias = TRUE, autorefresh = TRUE)

The default is to use the value in the user's environment variable
DISPLAY. |

Quartz is the graphic engine based on the PDF format. It is used by the graphic interface of MacOS X to render high quality graphics. As PDF it is device independent and can be rescaled without loss of definition.
If a device-independent R graphics font family is specified
(e.g., via par(family=) in the graphics package),
the Quartz device makes use of the Quartz font database
(see quartzFonts) to
convert the R graphics font family
to a Quartz-specific font family description.
Calling quartz() sets .Device to "quartz".
Line widths as controlled by par(lwd=) are in multiples of the
1/72 inch, and multiples < 1 are silently converted to 1.
