Dear Gurus,
R 2.11.1 on Windows XP.
This is a problem in interaction between R and pdftex.
I need to generate a plot with both open and filled circles. It is
simple enough, using pch=1 and pch=16.
The R pdf graphics output is going into pdftex 1.40.10 (MikTeX 2.8).
The R pdf is correct when viewed in other viewers. However, pdftex
fills the open circles. I can work around this problem by using
pch="o" for the open circles. However, that messes up the figure
legend.
Is it possible to use the pch argument of legend() to specify both a
symbol number and a character? I haven't found the way.
You don't need to. pch="o" is the same as pch=111 (the ASCII number).
See ?points.
Or is there some known work-around for the pdftex bug?
Well, pdftex is not a viewer and does not of itself process PDF
inclusions, but see ?pdf and the 'useDingbats' argument.
If you really think this is a bug in your LaTeX system, you should
report it. But you haven't shown us reproducible code, and similar
things have worked for me in the past.
Thanks!
