Hi Paul:

I very much appreciate your spending the time to help me here, and I hope we will get a nice how-to document from this for other novices---or at least a google-able record in the r-help archive.

  afmfiles <- 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")

    # Set up the mapping for "lucida" font family   postscriptFonts(lucida=postscriptFont("Lucida", metrics=afmfiles))     # Specify that the "lucida" font is to be used   postscript(file="lu1.ps", fonts="lucida");   l<- 40:80;
  plot(l,l,pch=l);
  dev.off();

$ grep LucidaBright-Demi lu1.ps

%%+ font LucidaBright-Demi
%%+ font LucidaBright-DemiItalic
%%IncludeResource: font LucidaBright-Demi

/LucidaBright-Demi findfont

%%IncludeResource: font LucidaBright-DemiItalic
/LucidaBright-DemiItalic findfont

but is also still includes the Helvetica font family, even though my intent is to get rid of them.

which seems to indicate that the Fontmap file was found. (Adding a "-GS_FONTPATH=." to point to the local directory is not necessary.)

$ pdffonts testembed.pdf

name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
Helvetica                            Type 1C      yes no  no      10  0


Also, looking at either lu1.ps or testembed.pdf with previewers shows that I am still using Helvetica fonts, not Lucida fonts. so something is still missing somewhere. (I also tried creating a pdf file directly under R, and though it gives me no error, and although the resulting pdf file claims to reference both helvetica and lucida fonts [and others], upon viewing, I can see that there are only helvetica fonts visible; no lucida fonts.)

further help and advice would still be appreciated.

Regards,

/iaw

  Right, the fonts are referred to in the PostScript or PDF file, but no font information is embedded. Now we move to the second problem I mentioned, embedding the fonts. Can you try using ghostscript? (see my first post)
