similar to: How to comment out entire code parts in Sweave files

Hi, is it possible to send some message to the console from within a .Rnw Sweave script, ie. when executing Sweave()? The background is that only in particular circumstances my script is doing some lengthy computations and I would like to print some status information to the console. It seems Sweave redirects all output though. Any suggestions? Thanks a lot for considering my question. All

Hi, I am very intrigued by the idea of integrating statistical analysis directly with a paper as Sweave does it. But as I am collaborating with several people and they won't have set up R and also they're very unlikely interested in learning it, I am concerned about how such an Latex/Sweave document will work on their side. Can they Latex-compile the document without having R / Sweave

Hi, has anybody encountered and solved the following problem? I continued work now on a different computer where I have also used Sweave successfully before. I can run Sweave() and it generates a .tex file. All code chunks are processed and translated to Latex perfectly fine but somehow only the \Sexpr{} tags are not parsed. This is an example .Rnw: \documentclass{article} \usepackage{Sweave}

Hello, I am very happy that I have Sweave and R to write my papers. But I still have to do some tables by hand since I have not found out how I can customize the latex tables produced by R further (I mainly use xtable()). Like for instance, I have a table which needs an extra row every few rows as a group header and sometimes I want some extra horizontal lines in the table and also a multicolumn

Hi, this is probably quite stupid but I have no clue what's wrong. Let's say I write the function hline <- function() { cat("\\hline \n") } and call hline() from within a Sweave chunk. Why is there no carriage return after the \hline in the resulting tex file? if I call hline() hline() in the chunk, then I get \hline \hline in the tex code without a linebreak in

Hello, using Sweave, is there any option to preserve the original aspect ratio of plots generated from R code? Consider this Sweave chunk: <<test,echo=F,fig=T,width=2,height=2>>= x <- 1:10 y <- sin(x) par(mar=c(4,4,0,4)) plot(x,y, xlab="x label", ylab="y label" ) @ In Latex, I want to produce a plot of width 2 but don't care about the

Hi, The 'br' instruction has the syntax: br i1 <cond>, label <iftrue>, label <iffalse> br label <dest> ; Unconditional branch If we know <cond>'s type must be 'i1', <iftrue><iffalse><dest> have to be of type 'label', why does the syntax have to specify them?

Hi, I want to insert a conditional branch in the middle of a basic block. To that end, I am doing these steps: (1) Split the basic block: bb->splitBasicBlock() (2) Remove the old terminator: succ->removePredecessor(bb) bb->getTerminator()->getParent() (3) Adding a new terminator: BranchInst::Create(ifTrue, ifFalse, cnd, "", bb); That seems to work, but later passes

Hello, I see some people including myself confused by the different object-oriented approaches in R (S3, S4, OOP, R.oo etc.). Would it be ok to collect examples and solutions for the different OO-packages in one package and add a vignette for documentation? (assuming I find time for this task) I mean in this case the package would not add data or functionality to R or serve as a companion

Hello R list members, I have a good object-oriented programming and software engineering background (mostly Java) and know some R. I'd like to learn more about functional programming concepts and its support and application in R. Do you have any recommendations (books, links etc)? I read (and like) "Programming in Scala" (Odersky) and just ordered "Funktionale

I'm experimenting using R as a report writer. I'm told LaTex is the destination for my quest. But ?latex() gives me an error. The package manager does not have it. The package installer can't find it. Where is it? It amazes me that there's not a built in "report" function that can produce the same kinds of reports that every report writer and data analysis software in

Hi, is there a function in R to convert data read with read.shape and which is originally in UTM coordinates into longitude / latitude coordinates? I found the convUL() function from the PBSmapping package but I have no idea how I could apply that to the read.shape object. Many thanks, Werner __________________________________________________ Do sragenden Schutz gegen Massenmails.

Hi, this is probably the easiest thing to do but I manage not finding the answer: I have a list with matrices of exact same format and headers. Now I would like to transform the list into an normal array. What is the proper way to do this? as.array changes the entire format and right now I only found the method of creating a new array, going through the entire list and copy the matrix in each

Hello,   ###  I created two classes "A" and "B". "A" is the superclass of "B".   setClass("A", representation(s1="numeric"),prototype=prototype(s1=8)) setClass("B",contains="A",representation(s2="character"),prototype=list(s2="hi")) myA=new("A") myB=new("B")   ####  I created

I have inputs to a function which are changing all the time - I pull these values from the internet. I then apply a function to the values. What I'd like to do is automate the process so it runs every one minute and adds the output of the function as a new element of a vector. Pseudo code: at Start time: input1_t0, input2_t0, input3_t0 function(input1_t0, input2_t0, input3_t0)

Hi! I have large matrices, one column per variable and I have a vector of factors / grouping symbols. Then I am computing subtotals for the groups but it takes pretty long and thus I wanted to ask if there is a better way to do it or if this is already the best way: subTotals <- function(x, groupvec) do.call("rbind",lapply(split(x,groupvec),colSums,na.rm=T)) Thanks reading my

Hi, I was wondering if anybody might have a reference for me: My R code is growing and getting more and more confusing. Thus, I figure it's time to switch to object-oriented again. I have done oo programming in C++ and Java before but the first few tutorial on R oo were a bit confusing for me. Is there any brief tutorial on oo programming in R especially for people who have done oo in Java

Hi, Before I reinvent the wheel I wanted to kindly ask you for your opinion if there is a simple way to do it. I want to merge a larger number of tables from different data sources in R and the matching criterium are country names. The tables are of different size and sometimes the country names do differ slightly. Has anyone done this or any recommendation on what commands I
