[R] TeXtext font encoding?

[ivo welch]

Dear R wizards:

Has anyone gotten the TeXtext font encoding to work?  If I execute:

if (is.null(postscriptFonts()$lucida)) {
  luafmfiles <- c("/usr/share/texmf/fonts/afm/yandy/lubright/lbr.afm",
                  "/usr/share/texmf/fonts/afm/yandy/lubright/lbd.afm",
                  "/usr/share/texmf/fonts/afm/yandy/lubright/lbi.afm",
                  "/usr/share/texmf/fonts/afm/yandy/lubright/lbdi.afm",
                  "/usr/share/texmf/fonts/afm/yandy/lumath/lbms.afm")
   postscriptFonts(lucida=postscriptFont("Lucida", metrics=luafmfiles, 
encoding="TeXtext"))
}

pdf(file = "test.pdf", fonts="lucida");
par(family="lucida");
plot( 40:50, 40:50, pch=40:50 );
dev.off();

the R code runs fine under 2.1.1, but the resulting .pdf file has an 
error:

$ pdffonts test.pdf

ghostscript 7.07 dies when I try to do the next processing step of 
embedding the fonts with ps2pdf13 .  These errors do not occur when I 
do not specify a font encoding.  (I believe I need this encoding for 
the math symbols, like '=', to appear in the right places.)

is this an R (enc file) bug or another mistake of mine?  as always, 
help would be highly appreciated.

sincerely,  /iaw
