Use of lwd = 0, lty = 2 in segments. (PR#230)
This may not be considered a bug but it is an incompatibility with S.
There was a convention in S that the graphics parameter setting
lwd = 0
is supposed to use the minimum possible line width on the device. It
is not clear what that means on modern graphics devices but there is
still code (like mine) that assumes something sensible happens with
lwd = 0
It seems that R's postscript

Postscript query: plotting long vectors
Hi,
I have a query about the maximum length of vector that can be plotted
in one go in a postscript driver. Try the following code (in 1.7.0;
version details below):
t <- seq(from=0, to=4*pi, length=200000)
y <- sin(t)
postscript(file="o.ps")
plot(t, y, type="l")
dev.off()
If I view the postscript file o.ps in "gv", it takes many seconds
before eventually

postscript failure manifests in plot.TukeyHSD
Hello R Developers,
Dear R-developers,
I ran some standard tests with currently (today morning) compiled R release
candidate in Linux R 2.12.1 RC (2010-12-13 r53843). Some of these tests used
plot.TukeyHSD function. This worked OK on the screen (X11 device), but
PostScript file could not be rendered. The following example had the problem
with me:

postscript printer breaking up long strings
For a long string in an axis title, or main title the postscript device
breaks apart the long strings into smaller strings. For example,
> postscript('linebreaktest.eps')
> plot(1,xlab='aReallyLongStringToSeeHowItBreaks',ylab='aReallyLongStringToSeeHowItBreaks')
> for(i in c(.6,1,1.4))text(i,i,'aReallyLongStringToSeeHowItBreaks')

postscript and lty
To the plot experts:
when creating a plot containing different lines, each with a special line
type, it may happen that the result of 'postscript()' is not readable by
ghostview (which may not be an R error, thus not bug report ;-).
This is the case when mixing lty as 0:6 and character or even when
using lty as character only.
Example:
postscript("test.ps")

one way to solve bad looking density plots in postscript
Hi,
When R generates density plots and these are exported to postscript(
a=matrix(1:100,10,10);image(a,col=rainbow(100);dev.copy2eps(file="image.eps")
)
The result often looks bad when rendered on screen. The help page states that this is because programs use anti-aliasing. That seems to be true - turning off anti-aliasing for gs (-dGraphicsAlphaBits=1) of in OSX's preview makes

xfig device
Hi, I am VERY interested in getting the xfig driver so that I can edit
graphical output from R. Searching through the mail archives and reading
documentation isn't helping. Is there or isn't there a working driver for
this purpose. How can I get it? I tried looking at the development version
of the tarballs, but I didn't find anything that looked promising in there.

paper size in postscript driver
I have a non-PS printer setup to print under linux using ghostscript as a
filter. This printer has two paper trays, one has letter paper, the other
tabloid size paper. If I print from a program that uses a PPD file to
configure the printer, like StarOffice or The Gimp, I can select the paper
size from a nifty list. If I select letter size, the printer print with
paper from the letter tray. If

Postscript Legends (or not)
I discovered a little problem when using the Windows NT release of R
1.0.1, and it's still there in R 1.1.0.
The boiled down version is this: I want to draw the following plot and
put it into a Postscript file:
x <- c(1,2,3,4); y1 <- c(1,2,3,4); y2 <- c(2,2,2,2)
Fred <- c(1,2)

Polyline toMicrosoft() change
Hi guys at mapstraction,
I made a change in the Polyline.toMicrosoft() function, in order to have
all the power that a VEShape has, for instance fill color. Below is the new

bug in arima? (PR#9404)
I don't think arima works exactly the way one would expect when there is differencing. What I think should happen is that by
default the mean of the differenced series is estimated and if include.mean=F, then it is not. This is not what happens. Instead
when there is differencing the include.mean argument is ignored.
Now I guess, someone could argue that the mean of the original series

bitmap copies of plots
Michael Lapsley was suggesting on R-help direct copies to gif/png/jpeg.
The following seems to do a sensible job for me of copying the current
device to any bitmap format supported by gs. The manipulation is needed
to work around assumptions made by postscript(), and I think better fixed
in postscript() (but not a couple of days before a release).
