Ivo,

This may not be exactly what you want, but...

Using the Hershey vector fonts, you can plot (using text()) a variety of
symbols.

See ?Hershey and demo(Hershey) for more information.

Here is an example:

plot(0:5, 0:5, type = "n")

text(1:4, 1:4, vfont = c("sans serif", "plain"), 
     labels = c("\\CL", "\\DI", "\\HE", "\\SP"), cex = 2)

The set of escaped characters in the vector for the 'labels' argument
are the codes for clubs, diamonds, hearts and spades, respectively.

HTH,
