Sweave: pass scale parameter to includegraphics?
Hi all I'm using Sweave and find it a treat. But one question: I use Sweave to create my pictures which are automatically included into LaTeX. For example, in the file test.Snw, I may have: % LaTeX stuff \begin{figure} <<fig=true,width=5,height=5>>= x1 <- seq(1,5, length=10) x2 <- sin(x1) plot(x1,x2) @ \caption{Plot} \end{figure} % More LaTeX This produces the LaTeX

Bug/Error in formatC? (Was: Why doesn't formatC( x, digits=2, format= "g")...)
Hi all After posting what follows, Duncan Murdoch suggested perhaps a bug in formatC, or an error on documentation. Any comments? In particular, bug, error or not, any ideas about how I can consistently get two significant figures to print? P. ---------- Original Message ---------- Hi all I am not a C programmer, but I am trying to understand formatC to get consistent printing of

Adding LaTeX cross-references into Sweave plots
Hi all I'm using Sweave and LaTeX, and love how they interact. But here's a different interaction I'm not sure how to achieve; I hope someone can help. I use a simple example, of course, to demonstrate. Suppose in my LaTeX document I have this: Here is a linear equation: \begin{equation} y = -1 + 3 x \label{EQ:example} \end{equation} This appears in the final product

Sweave issue: quotes in verbatim-like output print incorrectly
Hi all I love Sweave; use it all the time. But I recently received a new computer, and ever since I have had a problem I've never seen before. For example, I place the following in my Snw file: <<>>= sms <- read.table("http://www.sci.usq.edu.au/staff/dunn/Datasets/applications/popular/smsspeed.dat", header=TRUE) attach(sms) sms.lm <- lm( Time ~ Age*Phone,

The best way to end up with TIFF {Was: end up with WMF)
Hi all I posted a couple of days ago about how to end up with wmf files eventually in R for linux. The short answer was: you (probably) can't...and don't! The journal in question also accepts TIFF files, I am told (it's a physiology journal). So I adjust my question: What is the best way to get TIFF files out of R? It can't create them directly as far as I can tell.

Mixing lty specifications in legend
Hi all I have a plot with lines, one specified as (say) lty=1, using standard line types, and another as (say) my own spec: lty="51". I can't get legend to display both. Toy example: > plot(1~1) > legend("topright", lty=c("51",1), legend=c("My own","Standard")) Error in segments(x1, y1, x2, y2, ...) : invalid line type: must be

White background in PS pictures
Hi all I am using R to produce postscript pictures via the postscript command. I have never had any problems... until now, when I want to inlcude my .ps file is a LaTeX document *without* a white background. (If it's important, I'm using the prosper class with the whitecross option, so the background in blue.) I would like my .ps file to have a white background. If I read the help

Using xtable with summaries of lm objects

The best way to end up with WMF files
Hi all I am doing some stats work for a group of biologists who require windows metafiles (*.wmf) for their publications. To create these, I appear to have two choices: 1. Restart my machine in Windows and use savePlot 2. Keep my machine in linux, save as another format, then convert. I'd rather stay in linux; but how do I get wmf files? I looked at using ImageMagick's convert,

Plotting (mixed) line types and legends
Hi all I have a question about plotting line types and legends. Here's a short piece of code to demonstrate: x <- y <- seq(1,10) plot(x,y, type ="l", lty="33") lines(x,y+1, lty=1) legend( 8,2,legend=c("lty=1","lty=\"33\""), lty=c(1,"33") ) On my system (see below), the line types in the legend are not the same as in the

Two questions
Hi all Two questions: 1. I note that help for the postscript device claims "The postscript produced by R is EPS (Encapsulated PostScript) compatible...". It does not say it is EPS *compliant*. Indeed, the EPS produced by R includes a \showpage command which I believe (not that I'm an expert!) non-standard EPS. My question: Is there any reason why it is EPS compatible, but

Printing ps pictures with transparent b'ground
Hi all I wish to create a ps file of a picture produced in R. With my limited R, I see two ways: 1. Print direct to the postscript device 2. Print to the screen, and save to ps using dev.print. I want a white (not transparent) background. Option 1 above works fine, but 2 does not: even when I say I want a white background, I get transparent; perhaps I misread the help files. Here's some R

Building package: What does this message about rcompgen imply?
