unexpected behaviour of expression(sum())
I see you have both a scalable font (the first) and size-specfic fonts. My guess is that the scalable font is not encoded in the same way as the others: can you track down where it is coming from? Otherwise my list on FC3 is the same as yours (minus the duplicates, which are also puzzling). I have also just checked Exceed, which has the same list plus scalable fonts (and also has -adobe-symbol-0-0-normal--0-0-0-0-p-0-adobe-fontspecific -adobe-symbol-0-0-normal--0-0-0-0-p-0-sun-fontspecific -adobe-symbol-0-0-normal--0-0-100-100-p-0-adobe-fontspecific -adobe-symbol-0-0-normal--0-0-100-100-p-0-sun-fontspecific -adobe-symbol-0-0-normal--0-0-75-75-p-0-adobe-fontspecific -adobe-symbol-0-0-normal--0-0-75-75-p-0-sun-fontspecific which caused problems for 2.0.1 with getting bold symbols in some sizes, hence the second bug fix I mentioned). As a wild guess, do you have a font server as well as local fonts? Brian

I'm seeing inconsistent symbols from the same expression with the following code: expr = expression(sum(x, 1, n)) plot(1, main = expr, type = "n") text(1, 1, expr) Moreover, the inconsistency is reversed in r-devel compared to R 2.0.1. In particular, the main label shows a \bigoplus instead of \sum in r-devel, and the other way round in 2.0.1. demo(plotmath) shows \sum in both. Can anyone confirm? Is this intended behaviour (though I can't see how)?
No problem in "Version 2.0.1 Patched (2005-03-07)". I get \sum in both places. I do not see anything in the NEWS file suggesting a bug fix for this. I just installed "Version 2.1.0 Under development (unstable) (2005-03-11)" and do not see the problem there either. Both are under FC3.
We need to know both the device and the locale. Assuming this is X11, there are two fixes for font selection:
Yes, it's X11, with locale "C". It doesn't happen with postscript (I haven't tried anything else). I had tried on 3 different machines other than my desktop, but all remotely. Marc's reply suggested that this was a problem with X on my local machine, and I haven't yet had a chance to check on any others.
o X11() was only scaling its fonts to pointsize if the dpi
was within 0.5 of 100dpi.
o X11() font selection was looking for any symbol font, and
sometimes got e.g. bold italic if the server has such a font.
The main title in plot() and text() are asking for different sizes.
If Deepayan had problems with getting a valid (Adobe symbol-encoded)
font, this might vary by size which would explain the reported
differences.
Deepayan: can you please check what symbol fonts you have: the
pattern in R-devel is
"-adobe-symbol-medium-r-*-*-*-*-*-*-*-*-*-*"
(Ideally we would select on encoding, but that is usually
'fontspecific' so not helpful.)
I'm not really sure what I'm looking for, but everything I get seems to be 'fontspecific': deepayan $ xlsfonts | grep adobe-symbol-medium -adobe-symbol-medium-r-normal--0-0-0-0-p-0-adobe-fontspecific -adobe-symbol-medium-r-normal--0-0-100-100-p-0-adobe-fontspecific -adobe-symbol-medium-r-normal--0-0-75-75-p-0-adobe-fontspecific -adobe-symbol-medium-r-normal--10-100-75-75-p-61-adobe-fontspecific -adobe-symbol-medium-r-normal--10-100-75-75-p-61-adobe-fontspecific -adobe-symbol-medium-r-normal--11-80-100-100-p-61-adobe-fontspecific -adobe-symbol-medium-r-normal--11-80-100-100-p-61-adobe-fontspecific -adobe-symbol-medium-r-normal--12-120-75-75-p-74-adobe-fontspecific -adobe-symbol-medium-r-normal--12-120-75-75-p-74-adobe-fontspecific -adobe-symbol-medium-r-normal--14-100-100-100-p-85-adobe-fontspecific -adobe-symbol-medium-r-normal--14-100-100-100-p-85-adobe-fontspecific -adobe-symbol-medium-r-normal--14-140-75-75-p-85-adobe-fontspecific -adobe-symbol-medium-r-normal--14-140-75-75-p-85-adobe-fontspecific -adobe-symbol-medium-r-normal--17-120-100-100-p-95-adobe-fontspecific -adobe-symbol-medium-r-normal--17-120-100-100-p-95-adobe-fontspecific -adobe-symbol-medium-r-normal--18-180-75-75-p-107-adobe-fontspecific -adobe-symbol-medium-r-normal--18-180-75-75-p-107-adobe-fontspecific -adobe-symbol-medium-r-normal--20-140-100-100-p-107-adobe-fontspecific -adobe-symbol-medium-r-normal--20-140-100-100-p-107-adobe-fontspecific -adobe-symbol-medium-r-normal--24-240-75-75-p-142-adobe-fontspecific -adobe-symbol-medium-r-normal--24-240-75-75-p-142-adobe-fontspecific -adobe-symbol-medium-r-normal--25-180-100-100-p-142-adobe-fontspecific -adobe-symbol-medium-r-normal--25-180-100-100-p-142-adobe-fontspecific -adobe-symbol-medium-r-normal--34-240-100-100-p-191-adobe-fontspecific -adobe-symbol-medium-r-normal--34-240-100-100-p-191-adobe-fontspecific -adobe-symbol-medium-r-normal--8-80-75-75-p-51-adobe-fontspecific -adobe-symbol-medium-r-normal--8-80-75-75-p-51-adobe-fontspecific deepayan $ -Deepayan
