A graphics device is opened. For win.graph
, windows
,
x11
and X11
this is a graphics window on the current
Windows display: the multiple names are for compatibility with other
systems. win.metafile
prints to a file and win.print
to
the Windows print system.
bringToTop
brings the specified screen device's window to the
front of the window stack (and gives it focus).
windows(width = 7, height = 7, pointsize = 12, record = getOption("graphics.record"), rescale = c("R", "fit", "fixed")) win.graph(width = 7, height = 7, pointsize = 12) x11(width = 7, height = 7, pointsize = 12) X11(width = 7, height = 7, pointsize = 12) win.metafile(filename = "", width = 7, height = 7, pointsize = 12) win.print(width = 7, height = 7, pointsize = 12) bringToTop(which = dev.cur())
display |
indicates the purpose of the device. |
filename |
the name of the output file: it will be an enhanced
Windows metafile, usually given extension .emf or .wmf . |
width |
the (nominal) width of the plotting window in inches. |
height |
the (nominal) height of the plotting window in inches. |
pointsize |
the default pointsize of plotted text. |
record |
logical: sets the initial state of the flag for recording plots. |
resize |
controls the action for resizing plots. |
which |
a device number. |
All these devices are implemented as windows
devices, the
display
parameter selects which is actually used.
The size of a window is computed from information provided about the display: it depends on the system being configured accurately.
A graphics window is not allowed to be specified at more that 85% of the screen width or height: the width and height are rescaled proportionally. The window can be resized to a larger size.
If the filename
is omitted for a win.metafile
device, the
output is copied to the clipboard when the device is closed. A
win.metafile
device can only be used for a single page.
If a screen device is re-sized, the default behaviour is to redraw the
plot(s) as if the new size had been specified originally. Using
"fit"
will rescale the existing plot(s) to fit the new device
region, preserving the aspect ratio. Using "fixed"
will leave
the plot size unchanged, adding scrollbars if part of the
plot is obscured.
A graphics window will never be created at more that 85% of
the screen width or height, but can be resized to a larger size.
For the first two rescale
options the width and height are
rescaled proportionally if necessary, and if rescale = "fit"
the plot(s) are rescaled accordingly. If rescale = "fixed"
the initially displayed portion is selected within these constraints,
separately for width and height.
Using strwidth
or strheight
after a window
has been rescaled (when using "fit"
) gives dimensions in the
original units, but only approximately as they are derived from the
metrics of the rescaled fonts (which are in integer sizes)
The displayed region may be bigger than the `paper' size, and areas
outside the `paper' are coloured light grey. Graphics parameters such
as "din"
refer to the scaled plot if rescaling is in effect.
A plot device is opened: nothing is returned to the R interpreter.
