Hi there,
yet on the topic of greek letters and pdf plotting: when I run the
following code
pdf(file="temp.pdf")
mu=seq(from=-pi, to=pi, length=100)
plot(mu, sin(mu^2),
type="l",
xlab=expression(mu%in%(list(-pi,pi))),
ylab=expression(sin(mu^2)),
main=expression((list(mu,sin(mu^2)))))
dev.off()
I get a "proportional to" symbol in place of a "mu" and a
"not equal
to" in place of a "pi" (see attached file). If I run only
mu=seq(from=-pi, to=pi, length=100)
plot(mu, sin(mu^2),
type="l",
xlab=expression(mu%in%(list(-pi,pi))),
ylab=expression(sin(mu^2)),
main=expression((list(mu,sin(mu^2)))))
then the characters are displayed correctly.
I would like to know if there is any sort of fixes to this problem,
such as specifying the symbols font or embedding fonts into the pdf
file. Any help would be welcome.
Thanks in advance and best regards,
Eduardo Horta

Please do read the help page (and state your platform). This is s
known PDF viewer bug. E.g.:
If you see problems with PDF output, do remember that the problem
is much more likely to be in your viewer than in R. Try another
viewer if possible. Symptoms for which the viewer has been at
fault are apparent grids on image plots (turn off graphics
anti-aliasing in your viewer if you) and missing or incorrect
glyphs in text (viewers silently doing font substitution).
See also the section on 'Cairo fonts' in ?X11, which has a diagnosis
and workaround.

If I run onlyIn my PDF viewer (okular, debian LINUX) the file looks ok. This may very well be a problem with your pdf viewer. E.g. at work, we are running fedora and there I have experienced a number of problems like yours caused by a problem with font substitution in some version of the poppler library which is uses by many LINUX PDF viewers. Try to view the file in acrobat reader and possibly other viewers. Also: the files I had issues with printed correctly. cu Philipp -- Dr. Philipp Pagel Lehrstuhl f?r Genomorientierte Bioinformatik Technische Universit?t M?nchen Wissenschaftszentrum Weihenstephan Maximus-von-Imhof-Forum 3 85354 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/
