Hi Paul:

You are correct. it was the same little bug I hit on. Specifying the full (not the symlinked) afm filenames lets me run the code. No R error. yoohoo!

alas, the files don't seem to come out right. I can use these commands on the R postscript() and on the R pdf() device. they have an effect on both. (that is, if I grep for lucida in the resulting ps or pdf file, respectively, the word lucida appears in both files). alas, usage is another story:

$ pdffonts tonativepdf.pdf

name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
ZapfDingbats                         Type 1       no  no  no       5  0
Helvetica                            Type 1       no  no  no      10  0
Helvetica-Bold                       Type 1       no  no  no      11  0
Helvetica-Oblique                    Type 1       no  no  no      12  0
Helvetica-BoldOblique                Type 1       no  no  no      13  0
Symbol                               Type 1       no  no  no      14  0
LucidaBright                         Type 1       no  no  no      15  0
LucidaBright-Demi                    Type 1       no  no  no      16  0
LucidaBright-Italic                  Type 1       no  no  no      17  0
LucidaBright-DemiItalic              Type 1       no  no  no      18  0
LucidaNewMath-Symbol                 Type 1       no  no  no      19  0

This is not so great. I had hoped to get rid of the Helvetica fonts here. Moreover, if I run my "firsttops.ps" file through ps2pdf12, I see

$ ps2pdf12 firsttops.ps firsttops.pdf ; pdffonts firsttops.pdf

name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
Helvetica                            Type 1       no  no  no       9  0

So, it seems that the lucida font is not used, and therefore optimized away.

regards,

/ivo
