Re: [R] debug R device plot
Not sure if you ever figured this out, but I was just directed to this post. You need to look for a file (it may not be in your project directory) that contains ___LOCK in its file name and delete it. filehash creates this to prevent multiple writes to the same file at the same time and somehow it did not get removed correctly. tikzDevice uses the filehash package to cache font metrics and it must have gotten interrupted. -Cameron -- View this message in context: http://r.789695.n4.nabble.com/debug-R-device-plot-tp3403638p3545415.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] boxplot( ) headers with Greek letters, values, and text
Johnson, Roger W. wrote:
Any suggestions on how I can produce the same title using the boxplot
command?
If you use LaTeX you could try the tikzDevice package (
https://r-forge.r-project.org/projects/tikzdevice/ ). In that case you
would use:
main = paste('\\mu =',mu,', \\lambda =',lambda,', truncation =',truncation,
', N_T =',n)
a full example is:
tikz('myplot.tex')
boxplot(rnorm(100), main = paste('\\mu =',mu,', \\lambda =',lambda,',
truncation =',truncation, ', N_T =',n))
dev.off()
And in a tex file:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{figure}
\centering
\input{myplot.tex}
\caption{}
\end{figure}
\end{document}
and the symbols would get typeset by latex.

P.S. I am one of the authors of this package, so this post is a bit self
serving but we just released a beta version and are trying to get the word
out.

Re: [R] Getting file name from pdf device?
Rainer M Krug-6 wrote:
Hi
IU would like to modify the dev.off function, so that it automatically
compresses the created pdf.
I am thinking of doing the following in the modified dev.off:
1) Get the filename of the pdf device
2) close the device by calling the original dev.off()
3) compress the pdf file with a system call of pdftk.
If you are the one who initiated the pdf device shouldn't you know the name
of the file? in that case just do something like:
my.dev.off - function (file, which = dev.cur())
{
if (which == 1)
stop(cannot shut down device 1 (the null device))
.Internal(dev.off(as.integer(which)))
#system call (or something similar)
system(paste('pdftk',file))
dev.cur()
}
fn - 'myplot.pdf'
pdf(fn)
#plot stuff
my.dev.off(fn)

Re: [R] xtable formatting: RED for negative numbers?
Ken-JP wrote:
Is there a way to modify this code to generate RED numbers inside xtable

This post would probably have been better for R-help. Anyway, you can do it
easily by modifying print.xtable.R in the xtable package. If it is easier,
make a copy of that file, modify it, load the xtable package, then source
your modified version.
Basically change line 227 from
result[i] - gsub(-,$-$,result[i],fixed=TRUE)
to
result[i] - gsub(-,\\color{red}$-$,result[i],fixed=TRUE)
and then your code chunk becomes:
sample,echo=F,results=tex=
library(xtable)
x.ts - ts(rnorm(100), start = c(1954, 7), frequency = 12)
x.table - xtable( x.ts, digits = 1 )
print( x.table, floating = FALSE, math.style.negative = TRUE)
@
Here is the patch: http://www.nabble.com/file/p24727150/print.xtable.R.diff
print.xtable.R.diff
Here is the output I got:

Re: [R] Computer Modern
Mr Derik wrote:
I am trying to use computer modern fonts in postscript files for a latex
document. Ultimately I want to automate this through sweave.
Hi There-
I admit this is shameless self promotion but might I suggest the tikzDevice
package. I am one of the developers and we just pushed up a beta version to
r-forge that is quite usable. It enables graphic output in pgf/tikz format
that can be directly imported into LaTeX. The fonts in your graphic will
implicitly match that of your document. It also works well with Sweave, you
can see examples in the vignette.
Binary builds may not be available until tomorrow but you can install from
source
svn checkout svn://svn.r-forge.r-project.org/svnroot/tikzdevice
R CMD INSTALL tikzdevice/pkg
then:
vignette('tikzDevice')

Re: [R] postscript printer breaking up long strings
Ted.Harding-2 wrote:
In the graph shown in your URL above, the xlab and the ylab

Hi-
I am one of the developers of pgfSweave. The problem (although it is
considered a feature) is this (from https://svn.r-project.org/R/trunk/NEWS):
NEW FEATURES (in 2.9.0)
o pdf() and postscript() gain a 'useKerning' argument to place
strings using kerning (which had previously been ignored in
display but not in strwidth), based in part on an idea and
code from Ei-ji Nakama. The default is TRUE.
Kerning involving spaces is now ignored (it was previously
only used in the computation of string widths).
This is normally not a problem but converting to pgf and then to pdf causes
large gaps when the useKerning option is turned on. The following will cause
the long strings to not break.
postscript('linebreaktest.eps',useKerning=FALSE)
plot(1,xlab='aReallyLongStringToSeeHowItBreaks',
ylab='aReallyLongStringToSeeHowItBreaks')
for(i in c(.6,1,1.4))text(i,i,'aReallyLongStringToSeeHowItBreaks')
dev.off()
Kerning will be turned off by default in the latest snapshot of pgfSweave.

Re: [R] changing Swaeve output settings for .pdf and .eps - is there a way?
markheckmann wrote:
The pdf() settings do not affect Sweave settings when producing a .pdf
graphic. How can I change the Sweave default settings to e.g. 3 inch?
Also, even if you set the width of your plot to 3 inches, the plot will be
expanded to 80% of the textwidth by default. To disable this (i.e you set
width=3 and your plot is actually 3 inches) use
\usepackage[nogin]{Sweave}.
You will have to copy Sweave.sty to your local directory or to your texmf
directory for this to work.

There are other ways to control the size: it isn't always 80%. I
normally use something like \setkeys{Gin}{width=0.75\textwidth} to control

number of times in the same document. (Read the LaTeX docs for graphicx
to see the other
keys that can be set.)
The reason I suggested using the nogin option is because the default
behavior has always seemed very unintuitive to me. It seems that setting a
width and/or height parameter should be the only thing that needs to be done
to determine the size of the graphic. I know this is documented but I think
it is overly confusing to a new user. I know the first time I set width=3
and the plot still spanned 80% of the page threw me off.
