Rwin configuration | R Documentation |
The file ‘Rconsole’ configures the R GUI (Rgui
) console
under MS Windows and loadRconsole(*)
loads a new configuration.
The file ‘Rdevga’ configures the graphics devices
windows
, win.graph
, win.metafile
and
win.print
, as well as the bitmap devices bmp
,
jpeg
, png
and tiff
(which use for type =
"windows"
use windows
internally).
loadRconsole(file)
file |
The file from which to load a new ‘Rconsole’ configuration. By default a file dialog is used to select a file. |
There are system copies of these files in ‘R_HOME\etc’. Users can have personal copies of the files: these are looked for in the location given by the environment variable R_USER. The system files are read only if a corresponding personal file is not found.
If the environment variable R_USER is not set, the R system
sets it to HOME if that is set (stripping any trailing slash),
otherwise to the Windows ‘personal’ directory,
otherwise to {HOMEDRIVE}{HOMEPATH}
if HOMEDRIVE
and
HOMEDRIVE
are both set
otherwise to the working directory. This is as described in the file
‘rw-FAQ’.
Each of the files contains details in its comments of how to set the values.
At the time of writing ‘Rdevga’ configured the mapping of font
numbers to fonts, and ‘Rconsole’ configured the appearance
(single or multiple document interface, toolbar, statusbar on MDI),
size, font and colours of the GUI console, and whether resizing the
console sets options("width")
.
The file ‘Rconsole’ also configures the internal pager. This shares the font and colours of the console, but can be sized separately.
‘Rconsole’ can also set the initial positions of the console and the graphics device, as well as the size and position of the MDI workspace in MDI mode.
loadRconsole
is called for its side effect of loading new
defaults. It returns no useful value.
Users of these languages will need to select a suitable font for the
console (perhaps MS Mincho
) and for the graphics device
(although the default Arial
has many East Asian characters).
It is essential that the font selected for the console has
double-width East Asian characters – many monospaced fonts do not.
The GUI preferences
item on the Edit
menu brings up an
dialog box which can be used to edit the console settings, and to save them
to a file.
This is only available on Windows.
