[R] avoid using Dingbats symbols for points()

I came across with a tiny problem.
points(2, 3, cex=10, pch=21, bg="grey", lwd=0.3)
points(2, 4, cex=1, pch=21, bg="grey", lwd=0.3)
If I execute this I'll get a nice PDF. Fine.
But I want to edit this PDF with let's say by using Adobe Illustrator.
If I try to open it Illustrator shows up an error message:
Missing Type 1 fonts have been substitute with the default font.
Fonts with foreign encodings have been reencoded.
I can press OK and I get an image which shows the letter 'l' instead
of the points except for the first points() statement.
Then I read in ?pdf:
- Circle of any radius are allowed. Opaque circles of less than 10
points radius are rendered using char 108 in the Dingbats font: all
semi-transparent and larger circles using a Bézier curve for each
OK. But is there a way to avoid replacing a circle less than 10pt
radius by a Dingbats font? In other word I want to have a Bézier curve
Up to now I use a very stony way à la:
[draw a pie chart with only one segment]
stars(matrix(data=1, ncol=1), draw.segments = TRUE, scale = FALSE,
radius = FALSE, locations = c(2, 3.2), col.segments = "grey", add =
TRUE, labels = NULL, len=0.05, lwd = 0.1)
The "only" thing I have to do is to delete an anker point for the
segment. But if the plot has hundreds of points, well ...
I tried it out with R 2.6.2 and R 2.7 on Mac OSX 10.5.3 and Windows
XP; always the same.
I would be appreciate for any hints.
Thanks in advance!
