similar to: Thin frame line around R pdf output in LaTeX

Two things I think are some of the best developments in statistics and production are the lattice package and the beamer class for presentation in Latex. One thing I have not become very good at is properly sizing my visuals to look good in a presentation. For instance, I have the following code that creates a nice plot (sorry, cannot provide reproducible data).

I was trying to produced bagged importance estimates of attributes in earth using the caret package with the following commands:   fit2 <- bagEarth(loyalty ~ ., data=model1, B = 10)   bagImpGCV <- varImp(fit2,value="gcv") My bootstrap estimates are produced however the second command "varImp" produces the following error:    Error in UseMethod("varImp") : no

This may be asking too much, but I'm wondering if anyone has a solution (even a hack) for creating multiple (overlay) plots in an Sweave file and post-processing the overlays in beamer appropriately. For example, suppose I have a series of figure blocks in my .Rnw file: <<plot1,fig=TRUE>>= [stuff] @ <<plot2,fig=TRUE>>= [stuff] @ <<plot3,fig=TRUE>>=

I am failing to uncover Sweave chunks step by step using the LaTeX beamer class. The following minimal example: \documentclass{beamer} \usepackage{Sweave} \begin{document} \begin{frame}[fragile] In the year \uncover<2->{25}\uncover<3->{\Sexpr{5*5}} \uncover<4->{ <<echo=TRUE, print=TRUE>>= 5*5*101 @ } \end{frame} \end{document} leads to an error message when

Dear Friends, I not sure whether this is an Sweave or a beamer problem. The Rnw file: \documentclass[compress,smaller]{beamer} %\documentclass{article} %\usepackage{beamerarticle} \usepackage{Sweave} \title{Psychophysics II} \date{September 9, 2008} \begin{document} \frame{ \begin{Schunk} \begin{Sinput} > ro <- 0.2 > c <- seq(from = -3, to = 4, by = 0.1) > fn <- 1 -

Hi everyone, I suspect this is an easy task however I've not been able to accomplish it. I'd like to create an mtext title which has certain words bold, the rest not bold. So far I've been able to create one which is all bold, one which is all not bold and one which has bold and not bold superimposed on one another. Any suggestion would be appreciated. Many thanks, Joe Retzer # Not

Hi, has anyonne experienced problems between the LaTeX beamer class and Sweave? The following code does not work properly: ################################# \documentclass{beamer} \usepackage[latin1]{inputenc} \usepackage[T1]{fontenc} \usepackage{ngerman} \begin{document} \frame{ \frametitle{test} test <<>>= 1+1 @ } \end{document} ################################# Below is the

Hello, I'm trying to make a poster in Latex using the beamer poster macro (http://www-i6.informatik.rwth-aachen.de/~dreuw/latexbeamerposter.php), and use Sweave to add in R output. This works fine for adding graphics and tables, but if I want to put code in, the file fails to build in Latex. My Rnw file looks like \documentclass[final,hyperref={pdfpagelabels=false}]{beamer}

I think I have isolated a problem with integration between Sweave and beamer. Could you please see the file: http://www.mayin.org/ajayshah/tmp/bugdemo.Rnw Unfortunately, it uses some of my internal libraries, so you can't run it. When I put it through Sweave, I get: http://www.mayin.org/ajayshah/tmp/bugdemo.tex which is, of course, a generic latex file which you can read and

Using Latex and the beamer class, I would like to highlight code snippets. Does anybody know a suitable 'preprocessor' or 'filter' for R (and/or C/C++) code ? I have been including it in simple \begin{verbatim} ... \end{verbatim} and I know there is a better way -- in fact I saw it used a while back in some package I looked at. And I didn't write that down... What I am

I've generated a version of the classic dotplot of the barley data with library(lattice) data(barley) trellis.device("postscript", color=TRUE, file="barley2x3.ps") old.settings <- trellis.par.get() trellis.par.set("background", list(col = "white")) lset(list(superpose.symbol=list(pch=c(19, 1, 25, 2, 15, 22, 23),

Hello, I have seen instructions on how to embed Latex Computer Modern fonts into R, but these are the default serif fonts. I am trying to embed the default font used for Latex beamer (theme Warsaw), which is a sans serif font and may be the default LateX Computer Modern sans serif font. Does anyone know the names of the font files? Thanks Heemun

It is a trivial matter to adjust the linewidth of the axes and plot line in a 2D plot: x <- 1:10; y <- 1:10; par(lwd=2); # axis (and others) linewidth plot(x,y,"l",lwd=6); # plot linewidth Is there anything comparable to this for persp or wireframe? I've tried a number of ways, and the framebox/axes seem to be linked to the linewidth used in generating the

I'm sorry for having to post this, but I can't seem to find any solutions to this, which seems pretty simple, but then again... I've started playing with the example r news project and wanted to start adding some graphs, but replacing: \begin{figure} \vspace*{.1in} \framebox[\textwidth]{\hfill \raisebox{-.45in}{\rule{0in}{1in}} A graph goes here \hfill}

Hello, I' using the pdf() device with bg="transparent" to create plots to be used within a latex (beamer) presentation. Later on, I see that the background of my pdf() graphics is solid white in the final presentation. I'm using R-2.6.0, and I have also tried to set the version argument in pdf() to "1.5" and "1.6". Later versions are not accepted. Has

I was trying to create a multi-color silhouette plot (each cluster a different color) from clusters created by trimkmeans. This works straighforwardly on an object created from pam however my colors are interwoven when I try the same approach on clusters from trimkmeans. I also tried sorting the silhouette object using sortSilhouette which did not solve the problem. If anyone has a suggestion,

When i do presentation i have this workflow: I connect the beamer on my notebook so i have dualscreen. On my notebook screen i have all icons/windows i need. The things i want to show i move to the 2. desktopscreen (the beamer). If i want to be independent of the cable-end of the beamer i do this: i connect a second monitor to my notebook and i stream the screen of the 2. monitor with ffmpeg

This question is about including code and R results in Latex trough Sweave. It works fine and is of great help. Now may question is how to get the code and the output computed by R within a frame in Latex. Does any one have an idea on that. I tried \fbox, etc. but it seems to have problems with the code chunk generation of Sweave and I ger errors. I would appreciate any suggestion. I'll

Hello, I plot a 3D plot/surface using cloud function in lattice package. Several days ago, I post a question about how to remove the framebox out the 3D plot/surface. However, I think I don't make me understood clearly. I just hope to romove the outer rectangle or box around the box. Thanks again. Regards, Jinsong Zhao

Dear R-helpers, Here is a minimal .Rnw file which shows that builds do not work in frames that contain chunks of verbatim code: \documentclass[]{beamer} \author{} \date{} \title{Title} \begin{document} \frame[containsverbatim]{\frametitle{Here the build doesn't work} \begin{enumerate}[<+->] \item A \item \alert{B} \item C \end{enumerate} <<generateIQ>>= iq <-
