| xfig {grDevices} | R Documentation |
xfig starts the graphics device driver for producing XFig
(version 3.2) graphics.
The auxiliary function ps.options can be used to set and view
(if called without arguments) default values for the arguments to
xfig and postscript.
xfig(file = ifelse(onefile, "Rplots.fig", "Rplot%03d.fig"),
onefile = FALSE, ...)
file |
a character string giving the name of the file. For use
with onefile = FALSE give a C integer format such as
"Rplot%03d.fig" (the default in that case).
(See postscript for further details.)

onefile |
logical: if true allow multiple figures in one file. If false, assume only one page per file and generate a file number containing the page number. |

further arguments to ps.options accepted by

Although xfig can produce multiple plots in one file, the XFig
format does not say how to separate or view them. So
onefile = FALSE is the default.
The file argument is interpreted as a C integer format as used
by sprintf, with integer argument the page number.
The default gives files ‘Rplot001.fig’, ..., ‘Rplot999.fig’,
‘Rplot1000.fig’, ....
Line widths as controlled by par(lwd=) are in multiples of
5/6*1/72 inch. Multiples less than 1 are allowed. pch="." with
cex = 1 corresponds to a square of side 1/72 inch.
Only some line textures (0 <= lty < 4) are used. Eventually this
will be partially remedied, but the XFig file format does not allow as
general line textures as the R model. Unimplemented line textures
are displayed as dash-double-dotted.
There is a limit of 512 colours (plus white and black) per file.
