Re: [R] Postscript fonts
Thanks, The following piece of code demonstrates a problem I still have. pdf(file=fonttest.pdf,fonts=c(Helvetica)) plot(1:10,main=,xlab=) par(family=Helvetica,font=1) title(main=Helvetica) par(family=Helvetica,font=2) title(sub=Helvetica-Bold) par(family=Helvetica,font=3) title(xlab=Helvetica-Oblique) dev.off() The font= parameter seems not to be respected. I do not get bold or italics. What am I doing wrong or not understand here? My original problem was that I had not understood that the fonts parameter is absolutely necessary when opening the device when one wants to use par(family= ). BTW, this is R 2.3.1 on Windows XP.

[R] Postscript output encoding on Windows
With R 2.3.1 on Windows, I've noticed that it defaults to the WinAsci.enc encoding, which throws up an error when viewed with the default install of GhostScript/GSView (versions 8.51/4.7 respectively). I didn't have this problem prior to upgrading to 2.3.1 as I can view all my old PS graphs and they don't have the WinAsci encoding. I've got around this problem by adding encoding=CP1251.enc to the postscript call but it seems a little bizarre that the default WinAsci wasn't working. Any ideas what the problem might be? A problem with Ghostscript, a bug in R, or something strange about my installation (there shouldn't be)?? Should WinAsci be the default?

Re: [R] Postscript output encoding on Windows
It is WinAnsi, not WinAsci, and that may well be your problem. Vanilla R 2.3.1 uses WinAnsi (I have just re-checked), so there is `something strange about my installation'.

[R] postscript bounding box in trellis/lattice plot is wrong ?
Hi, a problem involving postscript bounding boxes: I'm composing three scatterplots into a single figure, postsript for publication. The individual scatterplots should be square, so the overall figure should have a roughly 1:3 sort of aspect ratio. By default however, the overall figure comes out nearly square, and the scatterplots are stretched vertically. I fixed this by adding aspect=1/1 to the individual xyplot() calls. This produces a figure that looks correct. However, the bounding box for the figure leaves way too much space above and below... as if it is still assuming that the figure is square rather than 1:3 in proportions. Is there any fix for this? Thanks for any advice Here's the approximate code (very simple): library(lattice) plt_hi[[1]] - xyplot(thedat[,ir] ~ thedat[,ic], aspect=1/1) ... plt_hi[[2]] - xyplot(thedat[,ir] ~ thedat[,ic], aspect=1/1) ... plt_hi[[2]] - xyplot(thedat[,ir] ~ thedat[,ic], aspect=1/1) trellis.device(postscript, file=thefile, color=F) print(plt_hi[[1]], split=c(1,1,3,1), more=T) print(plt_hi[[2]], split=c(2,1,3,1), more=T) print(plt_hi[[3]], split=c(3,1,3,1), more=F) dev.off() __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

For starters, you should heed the advice in ?postscript:
The postscript produced for a single R plot is EPS (_Encapsulated
PostScript_) compatible, and can be included into other documents,
e.g., into LaTeX, using '\includegraphics{filename}'. For use
in this way you will probably want to set 'horizontal = FALSE,
onefile = FALSE, paper = special'.
print(plt_hi[[1]], split=c(1,1,3,1), more=T)
print(plt_hi[[2]], split=c(2,1,3,1), more=T)

[R] postscript (eps) / latex / par(mfg=...) / problem!

http://tolstoy.newcastle.edu.au/R/devel/04a/0344.html
Namely that using par(mfg=...) with a postscript (eps) for inclusion with

however, it appears fine with gv.

Including the resulting file in a latex document like this...
begin{figure}
\centering
\includegraphics[width=\textwidth]{x.eps}
\caption[X]
{
Hello!
}
\label{xFig}
\end{figure}
The result is an upside down (flipped) version of my plot. I tried
rotating 180 degrees (based on similar problems people were having on the
list), but then it just gets worse (most of the plot is off the page). If
I convert the dvi to ps (dvips -Ppdf my.tex.dvi -o my.tex.ps) it gets
worse (a tiny speck where the image should be).
After removing the two mfg commands (which I use to add grid lines (not
shown for clarity)) everything is fine! Some how mfg is snarling things
up.
OK, I just had a brain wave (dont laugh). Here is a diff of the working
eps vs the broken eps...

[R] PostScript scatter plot, losing points at RHS

There is space for them, i.e. the plot is simply blank where they should be; and extending the height and width makes no difference. Version 1.9.0 (2004-04-12); running on Linux Fedora Core 2.

Re: [R] PostScript scatter plot, losing points at RHS
Assuming you did dev.off() or quit the session at the end, I cannot reproduce this (even with 1.9.0). If you did, it is almost surely a faulty viewer (so check the actual file): if not you would have an incomplete plot since you failed to flush the output file buffer.

posted to this list some time ago a very useful function ``plotSymbols'',
which can be slightly modified as follows:
plotSymbols - function (fn=1) {
i - 0:255
ncol - 16
opar - par(cex.axis = 0.7, mar = c(3, 3, 3, 3) + 0.1)

axis(3, at = 0:15)
axis(4, at = 1:16, labels = 0:15 * 16 + 15, las = 2)

You can use this function to see what you get under various font

There is a similar function called TestChars in the examples in

However, you are correct, in that not knowing (or more correctly, not

Ivo,
This may not be exactly what you want, but...
Using the Hershey vector fonts, you can plot (using text()) a variety of
symbols.
See ?Hershey and demo(Hershey) for more information.
Here is an example:
plot(0:5, 0:5, type = n)
text(1:4, 1:4, vfont = c(sans serif, plain),
labels = c(\\CL, \\DI, \\HE, \\SP), cex = 2)
The set of escaped characters in the vector for the 'labels' argument
are the codes for clubs, diamonds, hearts and spades, respectively.
HTH,
Marc Schwartz

[R] postscript plotting to 36 roll plotter
Hello, First, my thanks to the R developers; it is a wonderful tool and supports my development and production activities in many helpful ways. My problem is as follows: I want to make long (~ 20-30 feet) plots on a HP 755 (36 color roll plotter) using the R postscript command. I have tried paper=special with appropriate width and height, and everything seems ok from the postscript side. But the plot gets truncated to whatever -o PageSize I specify (which, of course, makes sense). But using -o w2592 (36 roll unlimited) truncates to letter. Enough words: here is what I am using now. postscript(|lpr -P hp755 -o PageSize=ARCHE, paper=special,width=ww,length=ll) This limits me to 48 inches (ARCHE=36*48). In summary, does anyone know the correct choice of parameters to get a roll plot without a predefined limit. I did set ps.options(paper)=default instead of letter and I am using R 1.8.1 on Linux. Thank you, Don p.s. I am not subscribed to this list, so cc'ing me would be appreciated. __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Re: [R] 'postscript' command within a function
Edoardo,
I'm wondering why
postscript(file=filename)
doesn't suffice, and you need to use eval instead?

hello all,
I am trying to print a ps file as part of a function as in:
func - function (..., filename=temp.ps) {
# some stuff
[...]
# plot
eval( cat(postscript(\,filename,\)\n, sep=) )
plot(...)
abline(...)
dev.off()
# more stuff
[...]
}
but it does not work. Nor it does with 'paste' instead of
'cat'. In
order to make it work I have to call:
postscript(temp.ps)
func(...)
dev.off()
I am wondering why is that? How can I make my call to
postscript within a
function sort of 'global' ??
thanks
Edo

[R] 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=20)
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 the axes appear, but then only one vertical line is
drawn within the plot area -- there is no sine curve. (this is on a
fast dual processor linux machine with 2Gb RAM.) This is clearly a
postscript problem, rather than a R problem, since reducing the length
of t down to something like 2000 solves the problem. By looking at
the file o.ps it looks like the line is drawn by one rlineto call
per point, followed eventually by a stroke after the last point.
I'm guessing that the postscript interpreter simply cannot remember so
many points in the path before it gets to the stroke.
The example above is artificial, but this problem appeared with a real
data set this morning. The fix was to replace the single call to
plot() with many calls to line(), breaking the t and y vectors into
more manageable chunks; in this way, each postscript path was
manageable and we got the plot.
I tried plotting the same long vectors in gnuplot by first writing
them from R:
write.table(cbind(t,y), sep=\t, file=eg.dat, row.names=F, col.names=F,
quote=F)
and then in gnuplot:
set term postscript
set output gnuplot.ps
plot eg.dat wi lines
This came out fine; in gnuplot.ps every 400 lines during the plot it
outputs currentpoint stroke M (M is defined to moveto). I had a
look at the gnuplot source (gnuplot-3.7.3/term/post.trm) and found
that it does keep count of the length of the current postscript path:
e.g. in the function PS_vector(x,y) we see (line 1122):
if (ps_path_count = 400) {
fprintf(gpoutfile,currentpoint stroke M\n);
ps_path_count = 0;
}
so every 400 points it draws the line so far and then continues.
(Matlab .ps files also seem to have regular MP stroke.
I had a quick look in the corresponding R code src/main/devPS.c and
could not see any counter. Would it be worth adding such a counter
and periodic line output to PS_Polyline?

[R] Postscript PBs
Hi, I use R 1.6.2 under Mandrake9.0. I've got a problem with the postscript files I try to creat. When I look to the file with ghostview it's ok. When I want to print it, I've got a blank page or a black page (fill of black encre) I changed the printer (guessing it was my driver printer), it was the same. Does anyone had the same problem and resolved it ? -- Cordialy Emmanuel POIZOT Cnam/Intechmer Digue de Collignon 50110 Tourlaville Tél : (33)(0)2 33 88 73 42 Fax : (33)(0)2 33 88 73 39 - __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] postscript problems
I am using R-1.6.1 and when I save a figure using
dev.print(file=figure.eps)
and then insert this figure into a LaTeX file (using
\includegraphics and the package graphicx) , the figure
obscures some nearby text (it gets blanked out by white).
Comparing the postscript file to that produced by an earlier
version of R I can see the extra lines marked with a star below:
%%Page: 1 1
bp
/bg { 1. 1. 1. } def *
0.00 0.00 841.89 595.28 r p2 *
204.83 90.14 318.71 513.85 cl *
204.83 90.14 318.71 513.85 cl
If I remove these 3 lines by hand the problem disappears, but
surely there is an easier way!?

[R] postscript and ps.option metrics
Good Afternoon All,
I am working on a project to generate a particular celeration graph that requires a
very specific height and width in the format of the postscript output.
I have attempted to specify my height and width parameters in inches as I found in the
R help documentation, but this produces a graph much smaller than what it should if
the standard metric is indeed inches.
Since inches do not work, I've tried to eyeball the metric by printing out different
iterations of the height and width parameters and overlaying a copy of the graph I
need on it. This is very time consuming (which I don't mind), inefficient (which I do
mind), and tedious (which I do mind) as the width axis (X axis in landscape format)
doesn't seem to be moving as the parameter decreases in iterations.
If someone has a few minutes, could you review the code snippet below and provide any
suggestions about possible revisions/additions to this? I've looked at it so long I
can't tell what might be glaringly wrong or missing.
Many Thanks,
Patrick McLeod

P.S.
The specific axis measurements (in inches) should be: height=5.4, width=8.1 in a
landscape format.

Re: [R] postscript: can't center plot
Deborah, Perhaps, a good idea is to use eps output to include it into a LaTeX document, in this manner you can format and layout your graphics exactly the way you want.

[R] Postscript linewidth errors
Nothing in Rbugs or Rhelp on this that I could see: [Redhat 7.3 (Intel); R 1.6.2] R Postscript output contains a bunch of the following commands: nan setlinewidth And GNU Ghostscript 6.52 chokes with: Error: /undefined in nan Operand stack: ... The figure is a fairly complex directed graph with varying linewidths. I am able to write the figure to the x11 and xfig devices just fine from within R, and even export to EPS from xfig with no problems. So it seems like a bug in the R postscript driver.

[R] postscript: can't center plot
One of our color postscript printers needs a slightly larger margin than the default, so I'm trying to send slightly smaller graphics to it, but all the extra margin I provide ends up at the right and bottom of the page. These are the relevant (I imagine) ps.options: $paper [1] special $width [1] 10 $height [1] 8 $pagecentre [1] TRUE I tried this on two systems, in two versions of R, and the output is identical. linux: R 1.6.1 (2002-11-01) mips-sgi-irix6.5: R 1.6.1 Beta (2002-10-28) I'll attach a postscript file, which is very simple but I think shows the asymmetry I'm talking about. I'll file a bug report if I should, but I thought I'd give y'all a chance to confirm the behavior or tell me I'm going about this all wrong. Debby lestat.ps Description: PostScript document
