Dear Paul:

Thank you for responding. I had thought I had imposed too much, and did not want to be a bother any more. In any case, this does not seem to work for me.

> postscriptFonts();

   # snipped a lot of fonts
$lucida
$lucida$family
[1] "Lucida"

$lucida$metrics
[1] "lbr.afm" "lbd.afm" "lbi.afm" "lbdi.afm" "lbms.afm"

$lucida$encoding
[1] "default"

        Failed to initialise additional PostScript fonts In addition: Warning message:
Font encoding not found in PostScript font database >

to make sure I have all the files accessible, I symbolically linked them into the current directory, too:

$ file *
lbd.afm: symbolic link to
`/usr/share/texmf/fonts/afm/yandy/lubright/lbd.afm'
lbd.pfb: symbolic link to
`/usr/local/share/texmf/fonts/type1/yandy/lbd.pfb'
lbdi.afm: symbolic link to
`/usr/share/texmf/fonts/afm/yandy/lubright/lbdi.afm'
lbdi.pfb: symbolic link to
`/usr/local/share/texmf/fonts/type1/yandy/lbdi.pfb'
lbi.afm: symbolic link to
`/usr/share/texmf/fonts/afm/yandy/lubright/lbi.afm'
lbi.pfb: symbolic link to
`/usr/local/share/texmf/fonts/type1/yandy/lbi.pfb'
lbms.afm: symbolic link to
`/usr/share/texmf/fonts/afm/yandy/lumath/lbms.afm'
lbms.pfb: symbolic link to
`/usr/local/share/texmf/fonts/type1/yandy/lbms.pfb'
lbr.afm: symbolic link to
`/usr/share/texmf/fonts/afm/yandy/lubright/lbr.afm'
lbr.pfb: symbolic link to
`/usr/local/share/texmf/fonts/type1/yandy/lbr.pfb'

the links are live, and the files are what they pretend to be. any more suggestions would be very highly appreciated.

sincerely,

/iaw

 Thanks to Brian Ripley for pointing out that that should be ...

 postscript(file="test.ps", fonts="lucida");
