plain text in Chinese can not be set
Hi there,
According to ?par, 'font' is an integer which specifies which font to
use for text, that 1 corresponds to plain text (the default), 2 to bold
face, 3 to italic and 4 to bold italic.
When I test Chinese character in pdf(), I found that 1 to bold face, 2
to italic, 3 to bold italic, 4 to symbol. and I don't find how to set
plain text. In the following code, the font to use

rgb to cmyk conversion is wrong in src/library/grDevices/src/devPS.c (PR#11509)
The conversion of RGB to CMYK takes place in PostScriptSetCol() starting at
line 2900 of R-2.7.0/src/library/grDevices/src/devPS.c

double c = 1.0-r, m=1.0-g, y=1.0-b, k=c;

"Too many raster images" in devPS.c
Hi,
I am finding the recently added [1] functionality of embedding raster
images into plots on R devices very useful! Thanks to Paul Murrell and
others for providing that. I noted that in

a macro is defined: #define MAX_RASTERS 64, and consequently, I get

More than two font in a plot
Hi there,
I am a Chinese R user. I hope to display Chinese character in a plot,
and than save it in PostScript format. I have read the article titled
"Non-Standard Fonts in PostScript and PDF Graphics", especially the
section about CJK fonts. I also tried the code:

[PATCH] virtual: Documentation: simplify and generalize paravirt_ops.txt
From: "Luis R. Rodriguez" <mcgrof at suse.com>
The general documentation we have for pv_ops is currenty present
on the IA64 docs, but since this documentation covers IA64 xen
enablement and IA64 Xen support got ripped out a while ago
through commit d52eefb47 present since v3.14-rc1 lets just
simplify, generalize and move the pv_ops documentation to a
shared place.

Autoconf / Windows package building problem for device package
Dear list,
Tadashi Kadowaki has developed a pdf device package
that allows to add hyperlinks and popups
to (currently) text, mtext and rect calls.
The package passes R CMD check (minor warnings) and compiles
on MacOS X and GNU/Linux, but we do not succeed in building
the package for Windows.
The current version of the package can be

Postscript device ignores title if it is too long. (PR#565)
Hi,
This may just be an inconsistency between terminal drivers, rather
than a proper bug.
If the main title of a plot is too wide to all fit on the plot, the
X11 driver prints as much of the title as it can, but the postscript
driver totally ignores the title.
Here's a simple example:
% R
> plot(runif(1000), main="a long xxxxxxxxxxxx title")

Postscript font bugs (and a suggestion) (PR#914)
Documentation and other bugs with postscript():
1. This code crashes R (it asks for a font that isn't there):
postscript()
plot(0:1,0:1)
text(0.5,0.5,'crash',font=6)
The bug appears to be in the FixupFont routine in plot.c; on line 236,
it checks that the font number is in the range 1..32. Later this
crashes PostScriptStringWidth in devPS.c, because only fonts numbered

patch for textspecial and defaultfont in xfig
Hello,
The current xfig device lacks the functionality to set the
textspecial flag and use the defaultfont in xfig. This is necessary
when you want to export to xfig and use interpreted text (e.g., $
\frac{1}{e}$ gets interpreted by latex). The attached patch adds this
functionality.
Why would you like to do this?

segfault in AIX

AIX 5.3. I'm using xlc 7.0, xlc++ 7.0 and xlf 9.1 in 32 bit

Comments on R-1.2.1 builds (PR#851)
The R-1.2.1 builds have gone fairly smoothly on most of my UNIX
architectures, but there were many warnings reported by the picky SGI
compiler that could be eliminated in future releases.
Generally, I have found the SGI compilers very helpful in ferreting
out portability problems, unused and/or obsolete variables, unexpected
datatype coercions, etc., and they compile faster than any other

Identifying graphics files produced by R
Oftentimes, I see graphs on the web that *look* like they've been
produced by R, but I can never be sure. Or can I? I notice that
PostScript files include a "%%%Creator: R Software" line, but do R
graphics drivers encode any identifying information in GIF or PNG
files more commonly used on the web? And of so, would such evidence
necessarily be obliterated in post-processing (e.g

Sound file quality
I'm building a phone-in demo system to use for introducing Asterisk to
prospective clients.
One of the things I'm wary of is their likely preconceptions that VoIP
systems will have poor audio quality.
As a result, I'd like to ensure that the voice prompts I'm using have the
best possible audio quality.
Is it possible to use sound files at higher than 8kHz sampling? My callers

margins with postscript device
I've been having a problem when printing plots to a HP DeskJet 2500C printer.
This printer, like most inkjet printers, has a large minimum bottom margin.
For most HP inkjet printers, the bottom 1/2" (left 1/2" inch for landscape)
of the page can't be printed too. The postscript device in R has a default of
1/4" margins between the paper edge and the plotting area. This

R-alpha: line types
Responding to my own post, after some hacking:
To fix the behavior of the following test code (the rect()s inherit the
lty set by the previous abline())--
x _ (1:100)/10
plot(x,sin(x))
abline(h=0,lty=2,col="red")
rect(1,0,2,0.5)
abline(v=2)
rect(3,0,4,0.5)
Here are some diffs (now all I have to do is wade through and get lwd
working properly ...)
