## XFig Graphics Device

### Description

`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`.

### Usage

    xfig(file = ifelse(onefile, "Rplots.fig", "Rplot%03d.fig"),
         onefile = FALSE, ...)

### Arguments

`file` | a character string giving the name of the file. If it is `""`, the output is piped to the command given by the argument `command`. For use with `onefile=FALSE` give a `printf` format such as `"Rplot%d.fig"` (the default in that case).
`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 `xfig()`: `paper` the size of paper in the printer. The choices are `"A4"`, `"Letter"` and `"Legal"` (and these can be lowercase). A further choice is `"default"`, which is the default. If this is selected, the papersize is taken from the option `"papersize"` if that is set and to `"A4"` if it is unset or empty. `horizontal` the orientation of the printed image, a logical. Defaults to true, that is landscape orientation. `width`, `height` the width and height of the graphics region in inches. The default is to use the entire page less a 0.25 inch border. `family` the font family to be used. This must be one of `"AvantGarde"`, `"Bookman"`, `"Courier"`, `"Helvetica"`, `"Helvetica-Narrow"`, `"NewCenturySchoolbook"`, `"Palatino"` or `"Times"`. `pointsize` the default point size to be used. `bg` the default background color to be used. `fg` the default foreground color to be used. `pagecentre` logical: should the device region be centred on the page: defaults to `TRUE`.

### Details

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.

### Note

On 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.
