Using pch you can use all the symbols in the current font, try:
plot(0:15, 0:15, type='n')
points( (0:255)%%16, (0:255)%/%16, pch=0:255 )
then do it again with
points( (0:255)%%16, (0:255)%/%16, pch=0:255, font=5 )
(font 5 is usually a symbol font, fonts 2, 3, and 4 are bold and italic
versions of the base font (font 1)).
If that does not give you enough variety in symbols then look at the
my.symbols function in the TeachingDemos package, this lets you create and
use your own symbols (though automatic legends are not available).
