I think that symbol is referred to as "R fraktur"; you can also get that via the symbol font, e.g., ... library(grid) grid.text(expression(symbol("\302"))) If you want an R fraktur that looks more like a Latex one, see http://www.stat.auckland.ac.nz/~paul/R/CM/CMR.html If you want the so-called "bold blackboard" fonts, for some devices at least, you should be able to access the font from your Latex distribution. For example, the following code grabs the psyb font from the pxfonts package and uses it with R's PDF device (the paths to the font .afm and .pfb files may be different on your system) ... # Tell R where the font .afm files are pdfFonts(pxfonts=Type1Font("pxfonts", paste("/usr/share/texmf-tetex/fonts/afm/public/pxfonts/", rep("pxsyb.afm", 4), sep=""))) pdf("pxfonttest.pdf") # Use the pxfont grid.text("R", gp=gpar(fontfamily="pxfonts")) dev.off() # Embed the pxfont so that readers and printers will # not substitute a different font embedFonts("pxfonttest.pdf", fontpaths="/usr/share/texmf-tetex/fonts/type1/public/pxfonts/") Paul p.s. There's no need to "install" the Hershey fonts; they come as part of R. -- Dr Paul Murrell Department of Statistics The University of Auckland Private Bag 92019 Auckland New Zealand 64 9 3737599 x85392 [EMAIL PROTECTED] http://www.stat.auckland.ac.nz/~paul/ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
