similar to: Sweave bug using 'FDR' in chunk label (PR#9567)

Dear list, Inspired by the original Knuth tools, and for paedaogical reasons, I wish to produce a document presenting some source code with interspersed comments in the source (see Knuth's books rendering TeX and metafont sources to see what I mean). I seemed to remember that a code chunk could be defined piecewise, like in Comments... <<Chunk1, eval=FALSE, echo=TRUE>>=

Hi all, first of all, I'm not an expert on R, I'm still learning, so sorry if this is a stupid question... I have a large dataset that is to big for my computer memory, and I found quite useful the package biglm. Now everything is working perfectly. But if I want the residuals, how I can do it? Let's say that we are running the example: > data(trees)>

Thanks for doing this Thomas, I have been thinking about what it would take to do this, but if it were left to me, it would have taken a lot longer. Back in the 80's there was a statistical package called RUMMAGE that did all computations based on sufficient statistics and did not keep the actual data in memory. Memory for computers became cheap before datasets turned huge so there

Hi, Consider the following (much simplified) Sweave example: -------------- First, we set the value of $x$: <<chunk1,eval=FALSE>>= x <- 1 @ Then we set the value of $y$: <<chunk2,eval=FALSE>>= y <- 2 @ Thus, the overall algorithm has this structure: <<combined,eval=FALSE>>= <<chunk1>> <<chunk2>> @

How exactly should I go about turning off annotation when running Stangle (Rtangle) with "R CMD Stangle myfile.Rnw"? Ideally I would like to be able to turn annotation off and on for individual code chunks, or maybe better, to annotate only named chunks. Are either of these things easily done? Is there some way to figure out this sort of thing without reading through the source code

Hi, I'm using the Sweave and I would like include codes of the R in my LaTeX file. I extracts the R code with Stangle (), whose name is Relatorio.R but I can't include it in the Latex file as an appendix. Suggests?

Hi, Recently I saw a couple of cases in which the package vignettes were somewhat complicated so that Stangle() (or knitr::purl() or other tangling functions) can fail to produce the exact R code that is executed by the weaving function Sweave() (or knitr::knit(), ...). For example, this is a valid document that can pass the weaving process but cannot generate a valid R script to be source()d:

Trying to Stangle / Sweave a file $ cat vignette.Rnw %\VignetteEngine{knitr} \documentclass{article} \begin{document} \end{document} results in a misleading error message: ~/tmp$ R CMD Stangle vignette.Rnw Error: Vignette engine package not specified Execution halted when what is missing is the full specification knitr::knitr; 'vignette engine package and function not specified' ?

[I originally emailed this to Friedrich Leisch but got no response and I just wanted to make sure it made it in before release.] While working with Stangle(), I noticed a problem when using 'split = TRUE'. Particularly, when there are two chunks where one chunk's name is a prefix of another chunk's name, then the two chunks will be written to a single file rather than two

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}

Hello List, I have been using Sweave for my homework this last quarter and have been very impressed at how much time and effort it saves me. I, however, have run up against a problem which I have not been able to solve using any of the Sweave/LaTeX tricks I know. I work through my homework one problem at a time, typesetting equations and writing R code, etc. and occasionally use

Hello all, A few years ago, I added the inalloca feature to LLVM IR so that Clang could be C++ ABI compatible with MSVC on 32-bit x86. The feature works, but there is room for improvement. I recently took the time to write up a design using token values that will hopefully be better named and easier to work with and around. For the technical details of the proposal, I've written up the RFC

Sorry, I forgot to include a reproducible example on my last e-mail but here it is: Since the file is large to be included here: The path to the foo.Rnw examples is: www.stat.umn.edu/~charlie/Sweave/foo.Rnw and is suppossed to produce a pdf like this one: http://www.stat.umn.edu/~charlie/Sweave/foo.pdf I have downloaded MiKTEX but I don't know how to make it work. Sweave and Stangle seem to

Hi list, I need to process a Rnw file and and a csv file (both are encoded in UTF-8) under Windows XP (R Version 2.11.0, i386, mingw32). I can source and run the Rnw file: > Stangle("Bericht.Rnw") Writing to file Bericht.R > source(file("Bericht.R", encoding="UTF-8")) which runs fine, but running Sweave() failed: > Sweave("Bericht.Rnw")

I am working on a Windows XP machine with R 2.10.1 and a recent installation of MiKTeX 2.8. I use LyX (www.lyx.org) to write documents and have it set up to run Sweave, Stangle, and make the PDF through R using a batch script and a MakeSweave.R file. This system worked just fine until I ran some MiKTeX updates yesterday. This is a bit embarrassing as I helped produce a "How-to" guide to

I have obtained from transfer functions, the state space matrices for the following state space model. x* = Ax + Bu y = Cx + Du I have A, B, C, and D, now I would like to take the exogenous inputs and simulate the data using the state space model. I know there is a simulate function in the package dse1, but I am unsure as to what type of TSmodel to create to put into it. Could anyone give me

Hi, This is (presumably?) a bug in R 1.7.0 under Windows. I have not tested it on other systems. Attachment of packages is case sensitive but not library(), resulting in multiple loadings of the same package if the library name is spelled differently. The following example loads the `tools' package, once as `tools' and once as `Tools'. This behavior is the same with all packages and

Is there a procedure for suggesting changes to HELP files of the core R distribution? If yes, what is it? If it would be considered a friendly gesture, I could find the relevant *.Rd file and submit a suggested modification to it someplace. Alternatively, I could just send suggestions someplace if they would receive appropriate consideration. On many occasions, I think of

As a user, I am always annoyed beyond measure that Sweave vignettes precede the code by a command line prompt. It makes running examples by simple copying of the commands from the vignette to the console a pain. I know the idea is that it is clear what is the command, and what is the output, but I'd rather precede the output with some kind of marking. Is there any other solution possible /
