Known issues

• This function is only available when the cairo graphics library is configured with FreeType and Fontcofig support.

• R math symbols are supported,but require a "Symbol" font with the Adobe symbol encoding. At the time of this release the authors are unaware of a free version of this font, however they do exist on Windows and Mac OS X.

Details

This function sets the fonts for Cairo graphics devices globally; previously opened Cairo graphics devices will also use these fonts. The argument names correspond to the five values of the graphical parameter 'font', i.e. regular is 1, bold is 2, italic is 3, etc.

For an explanation of fontconfig patterns, see CairoFontMatch.
