Hi guys,
to make it easier, here is a simple case with the same issues. I use
the short function below to make the attached PS file.
Things to fix:
-) the greek letter "lambda" is not printed, while "mu" is printed
(see the plot command)
-) the annotation inside the plot area: the "+-" symbol and "(K)"
overlap with the substitute for tmed and tstd respectively (see the
text command). Also, how can I set the number of decimal digits for
tmed and tstd? (option(digits=4) does not work )
I would have thought one would do any formatting (of digits) outside
the text( ...substitute(...),...) setting.
Moreover, I'd like to make the characters thicker. Is there any way?
Which characters? There is a bold() option within plotmath.
Finally, once I close the R session without saving it (I answer "n"
when quitting), the content of the ps file is erased.
Now _that_ is weird. A file should have been created in your default
directory and closing R should not have made it go away.
Do I miss something in writing the function?
Perhaps. (But you certainly missed something in writing the question.)
When I remove the family="ComputerModern" from the postscript call, I
start seeing lambda. ,,,, And the other spacing weirness also
resolves. I am on a Mac and ComputerModern is not one of the
pdfFonts() on my machine. The list of available fonts varies widely
across various OSes and devices about which you have given us no clues.
