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

Dear R list, I'm using R 2.15.2 with TeX Live 2009 and ESS 12.09 . I have a R project in the '/home/r/Documents/myproj/', which is my working directory (where I have the .Rnw file). Inside the document I have several "setwd()" to collect the datasets I use. After I compile from the terminal using "R CMD Sweave myproj.Rnw", I receive the error: Error in

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?

Dear all, There seems to be a problem with named chunks in Sweave with the version of R under development (downloaded yesterday). When I sweave the file toto.Rnw described at the end of this mail (Ubuntu 10.04 LTS), the function Sweave returns an Internal error: > utils::Sweave("toto.Rnw") Writing to file toto.tex Processing code chunks ... 1 : echo term verbatim (label=a) 2

Hello, I wrote a function create_report that calls the function Sweave. create_report shall be used to create a pdf-report about an lm-Object which is passed as an argument to create_report. I try to use an object sel_model, that is created within the function environment of create_report and later on used within the first code chunk of the file report_template.rnw. When I use following code I

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 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'

Hello All, Have recently started learning Sweave and Knitr. Am now trying to learn odfWeave as well. Things went pretty smoothly with Sweave and Knitr but I'm having some trouble with odfWeave. My understanding was that odfWeave should work in pretty much the same way as Sweave. With odfWeave, you set up an input .odt file in a folder, run that file through the odfWeave function, and then

I have a code junk that produces a figure. In my special case, however, data does not always exist. In cases where data exists, the code chunk is of course trival (case #1), however, what do I do for case # 2 where the data does not exist? I can obviously prevent the code from being executed by checking the existence of the object x, but on the Sweave level I have a static figure chunk. Here an

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

Hello all, Sometimes I get to make an R code chunk (in Sweave) which is longer then the margins of the page. Is there a way to force it to "go to the next line" (in Sweave) once that happens? Here are two cases this happens in the resulting .tex file (one is a "hard" case, and the other is simpler) \begin{Schunk} \begin{Sinput} >

Hi, following issue: Sweave is running the R code to generate figures three times under standard behaviour, twice if run with eps=FALSE, once if run with eps=FALSE,pdf=FALSE. However, ideally, I'd want it to run once to generate pds with eps=FALSE being set. How come this isn't so? Am I missing something? Basically, my R figure code is expensive to run. I can of course move the

I've noticed a change in behavior in R 2.12.0 from 2.11.1 regarding the treatment of absolute paths in the file argument of Sweave in a Windows environment. Consider the minimal Rnw file, attached and reproduced below my signature in case .Rnw files get stripped. This file is stored on my (Windows) computer in H:/My Documents. Using an absolute path with the standard window's

> See the 'Writing R Extensions' manual, specifically > Creating R Packages -> Writing package vignettes thank you, i saw this entry. However, this entry is rather about how to include documents (in particular Sweave-based) into a package. But I have meant smth else. Let me explain in example. Today I use emacs as environment for my R-sessions. I am quite happy to use

Dear List, First off, my deepest gratitude to the Sweave developers: this tool has improved my quality greatly. A question in my work I use \Sexpr{} statements scalar values and the xtable package for all manner of tables. What I'd like to do is to use a vector inline, rather than a whole separate table. Something like: %%%%%%%%%%%%%%%% begin code % Latex junk % Sweave block:

Dear R and Sweave users, Is there a way to have optional sections in a Sweave-generated report document, complete with section header(s), text and code chunks? In other words, I'd like for my report to include or omit certain sections based on the data itself. For example, If I examine the input dataset early on in the report and set a variable has_daily_data = TRUE, then I'd like to

Dear guRus, I would like to loop over a medium amount of Sweave code, including both R and LaTeX chunks. Is there any way to do so? As an illustration, can I create a .tex file like this using a loop within a .Rnw file, where the "1,2,3" comes from some iteration variable in R? ################################################ \documentclass{article} \usepackage{Sweave} \begin{document}
