I would notice this error compiling a Sweave document after I updated R from version 2.14.2 to 2.15.0: Error in driver$finish(drobj) : the output file 'MyDocument.tex' has disappeared Calls: <Anonymous> -> do.call -> <Anonymous> -> <Anonymous> Execution halted Do you have any suggestion?

Hi, I'm working with Sweave and I have some trouble generating table. The R code is: print(xtable(myTable, caption ="", label="tab:myTab", digits=3), tabular.environment='tabular', floating=TRUE, caption.placement="top",size="\\scriptsize") and the resulting LaTeX table is: \begin{table}[ht] \begin{center} \caption{Principal

Hi, I use the lda function from the MASS package to classify some samples according to some chemical properties. If I run lda without cross validation all is ok but, if I run lda with cross validation, the R consol say: resLDA <- ldaRedOx <- lda(Activity ~ TRedOx[,1:6], CV=TRUE, data=dfDataRedOx, subset=train) predLDA <- predict(resLDA, newdata=dfDataRedOx[-train,])$class >

Hi, is there a way to collapse/expand the Sweave chunks? Best Riccardo

Hi, I need to export to LaTex the summary of a PCA. So: myPCA <- prcomp(myDF) mySummary <- summary(myPCA) # print(xtable(mySummary)) How can I export to LaTeX not all the summary but only the first nPCs?? Best Riccardo

Dear list, I have some .xls files that I need to read into R. I am able to do so using read.xls in the gdata package, however the helper functions sheetNames and sheetCount fail. This is the error: Unable to open file '~/SharedFolder/MyData/mydata.xls'. Warning: running command ''/usr/bin/perl' '/usr/local/lib/R/site-library/gdata/perl/sheetCount.pl'

Hi, I'm working with support vector machine for the classification purpose, and I have a problem about the accuracy of prediction. I divided my data set in train (1/3 of enteire data set) and test (2/3 of data set) using the "sample" function. Each time I perform the svm model I obtain different result, according with the result of the "sample" function. I would like

(Besides Paul, who's busy?) I just need one question answered: I keep reading the docs, and given the old traditional /var/www I get that part of trac should be installed in /var/www/trac/<myproj> (I think); what I can't figure out is whether there is *anything* under the document root, that is, /var/www/html/trac/<myproject>. Anyone have a clue? Do I even need it as a

Hi, I am using cwrsync ver 2.1.5 over SSH to connect to myproj@sourceforge.net and facing some problems and not sure how to go about it. Below is the full text of the result when I run the batch file. Was wondering if anyone has seen any similar issue. Any thoughts/help is much appreciated. ------------------------------------------------ Tunnel: ssh Command to run: "C:\Program

Dear all, Sweave chokes when using "\\" in the path to the Rnw file. Using "/" works fine. The problem is that Eclipse+StatET uses "\\" in the filename. And example of the error, traceback and sessionInfo are given below. Best regards, Thierry > Sweave("Q:\\BMK\\cursussen\\interne_opleiding\\deelnemerslijst.Rnw", syntax="SweaveSyntaxNoweb")

We are starting a local LLVM backend project (using svn) and are looking for a mechanism to periodically update to later LLVM releases. Certainly, this seems like it would be a relatively common use case and I expected a google search would reveal several options. However, I didn’t really find anything. Perhaps I’m not looking for the right keywords, if so please help me out and point me to any

I've been using the following code to plot using Sweave in version 1.9.1 library(RODBC) library(lattice) channel <-odbcConnectExcel("h:/water.xls") data <- sqlQuery(channel,"select * from `Sheet1$` where Test = 'TOC' and (Valve='5010-05' or Valve='8030-V26' or Valve='1180-08' or Valve='5040-08')") odbcClose(channel) srt <-

Not sure if anyone needs this, but I have successfully been running rspec/trunk with autotest for a few days now on a non-rails project. The process is pretty simple: 1. Put rspec into vendor/plugins/rspec (on externals, or simply frozen) 2. Add autotest/discover.rb: Autotest.add_discovery do "myproj" end 3. Add autotest/myproj.rb: require File.dirname(__FILE__) +

I have found a quite strange (to me) behaviour in Sweave. It only occurs in the following situation: 1. define a variable in one chunk 2. use it within a subsequent figure-generating chunk 3. delete it at the end of that same chunk Then the Sweave driver chokes, not finding the variable name when generating the figure Example: % document bug2.Rnw \documentclass{article} \usepackage{Sweave}

Dear List: I am encountering an error that I can't resolve. I'm looping through rows of a dataframe to generate individual tex files using Sweave. At random points along the way, I encounter the following error Error in file() : cannot find unused tempfile name At which point Sweave halts. There isn't a logical pattern that I can identify in terms of why the program stops at

if anyone has a minute maybe you can help with a newbish problem im having with radrails v0.6.3. If i try to generate a migration through the ''generators'' panel i get error messages like this: myProj> ruby script/generate migration newtest myProj> -e:3:in `load'': No such file to load -- script/generate (LoadError) from -e:3 Although the generators work fine

Depending on an R computation I would like to include an Sweave documents in the main Sweave document. How can I do it? So I was thinking .... to use Latex features : \newif\ifpaper \ifpaper \SweaveInput{"my1.Rnw"} \else \SweaveInput{"my2.Rnw"} \fi But how do I set paper to true or false given an \Sexpr ?? \papertrue % or \paperfalse Any ideas? cheers -- Witold

Dear expeRts, I have a master file master.tex containing the preamble and which inputs (via \input{chapter01}, \input{chapter02}, ...) chapters. The chapters are .Rnw files. My goal is to use patchDVI::SweavePDF to compile the chapters (say, chapter.Rnw) individually (each chapter starts with sourcing Sweave preliminary settings). The first problem is the following. If I execute (in the shell)

Hello, I found my Rnw file generated strange symbols in pdf file. For instance, on page 4 of the following file, http://cran.r-project.org/web/packages/cts/vignettes/kf.pdf you can see Belcher et~al on line 2, and Figure~1 on line 5. The symbol ~ should not appear in the pdf file although the symbol was in the original Rnw file (something like Figure~\ref{...}, section~\ref{...}). On page 1,

Hi All -- I'm not sure this is the natural place for this question, but this list is the place with the best Sweave-TeXShop-sync discussion so far. My problem is that sync+Sweave+TeXShop works sometimes and not others, and it's not consistent. The failure, in which sync from PDF opens the .tex file instead of the .Rnw file, always comes after a code chunk. If I start from a simple
