Thank you for your help.
I've read all the documentation I can find and I still can't get this to
work.
postscriptFonts()
in my console produces a list of fonts already mapped yes?
one of which is:
$ComputerModernItalic
$family
[1] "ComputerModernItalic"
$metrics
[1] "CM_regular_10.afm" "CM_boldx_10.afm" "cmti10.afm"
"cmbxti10.afm" "CM_symbol_10.afm"
$encoding
[1] "TeXtext.enc"
attr(,"class")
[1] "Type1Font"
So modifying the code of Paul's website:
pdf("destructiontest.pdf")
par(family="ComputerModernItalic")
demo(plotmath)
dev.off()
Should give me what I want. Instead I get a file which can't be opened and
25 warnings which all look like this:
25: In text.default(2 * c - 0.5, -r, title) :
font family not found in PostScript font database
But you are creating a PDF file, not a PostScript file, and if you look
at names(pdfFonts()) you'll see that there is no ComputerModernItalic there.
I've tried the "Test full Adobe Symbol font" code off Paul's website with
the fonts loaded into my working dir as described. I get 35 warnings of the
type:
1: In grid.Call.graphics("L_text", as.graphicsAnnot(x$label), ... :
font width unknown for character 0x7f
and a pdf with dots in place of every character.
I can open the example pdf on Paul's website and see the correct CM font so
my viewer must be working.
Any other ideas would be welcome.
Is it possible that you have set the fonts up using PostScriptFonts()
when you should really be using pdfFonts() ?

I am trying to use computer modern fonts in postscript files
for a latex document. Ultimately I want to automate this through
sweave. I've read the documentation ans have tried the following
code to use lattice to produce a graph using computer modern:
library(lattice)
library(grid)
testPlot=(
xyplot(seq(1:10) ~ seq(1:10),
main="one to ten",
xlab="the quick fox",
ylab="jumped over the lazy brown dog",
xlim=c(0,1),
ylim=c(0,1),
col="black",
type="l" ,
lwd=2
)
)
setwd("C:\\R_folder\\CMtests")
postscript("cm_test.eps", width = 4.0, height = 3.0,
horizontal = FALSE, onefile = FALSE, paper = "special",
family = "ComputerModern", encoding = "TeXtext.enc")
print(testPlot)
dev.off()
This produces a plot with courier.
I am using R 2.9.0 on a windows XP machine. I did manage to produce
one plot with CM as the font so I know it's possible with my set up.
I can't get back to that. Please help me with the code.
Thank You
I think you may need to also use the "fonts" pAramater to postscript().
See in '?postscript':
fonts: a character vector specifying additional R graphics font
family names for font families whose declarations will be
included in the PostScript file and are available for use
with the device. See 'Families' below. Defaults to 'NULL'.
Since the Computer Modern family is most probably not built in
to your printer, the PostScript file will need to include font
definitions for these fonts. If I understand aright, this is what
would be achieved by appropriate use of the "fonts" parameter.
If the font definitions are not included, the calls for them will
not be recognised by the printer which may then substitute a default
(likely to be Courier).
See also the section "TeX fonts" in '?postscript'.
Ted.
