Hi, I'm currently writing an S4/Oracle interface, and as Brian Ripley points out, the .Call interface is the key. The good news is that the S part (I presumed the R part as well) is remarkably straight- forward by using the .Call facilities to create list and other S objects directly from C. I'm following Brian's suggestion and printing the R-external documentation --- I need to

I'd like to propose that the whenever the length of condition passed to an if or a while statement differs from one, an error is produced rather than just a warning as today: > x <- 1:2 > if (x == 1) message("x == 1") x == 1 Warning message: In if (x == 1) message("x == 1") : the condition has length > 1 and only the first element will be used There are

Hi, I'd like to construct an R list object in C++, fill it with relevant data, and pass it to an R function which will return a different list object back. I have browsed through all the R manuals, and examples under tests/Embedding, but can't figure out the correct way. Below is my code snippet: #include <Rinternals.h> // Rf_initEmbeddedR and other setups already performed

I would like to create \examples{} in the manual dynamically, and while it is possible to do this with a \Sexpr at the top level, R CMD check issues a warning for it. (See below.) Is it intentional that \Sexpr is not allowed at the top level? The Rd grammar allows this, but R CMD check does not. Is there any other way to generate/modify the \examples{} section dynamically? Thanks, Gabor In

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:

Hi: I am trying to create a dynamic latex table using \Sexpr{} but it's not evaluating it. I also tried the example below without Sweave and also fails. I have also copied the Sweave.sty to my working directory but nothing seems to work. Do I need to have certain package in order to run \Sexpr{}? \documentclass[a4paper]{article} \usepackage{C:/R/R-2.8.1/share/texmf/Sweave} \begin{document}

Hi, another Rd related issue I encountered is that if an error occurs in an \Sexpr in an Rd file, then on get the following error: * checking for portable compilation flags in Makevars ... OK * checking for portable use of $(BLAS_LIBS) and $(LAPACK_LIBS) ... OK * checking examples ... ERROR Error in paste(before, x, after, sep = "") : object 'exfile' not found Execution halted

Hi all, Currently Sweave does not format the (especially numeric) value in \Sexpr{}, and I often have to round() the numbers explicitly, otherwise I will get more than 10 digits, which is not necessary for me in most cases. Is there a way to specify the number of digits to be kept for values in \Sexpr{}? e.g. can we make \Sexpr{} respect getOption('digits')? Thanks! Regards, Yihui --

I am sure it is just me not understanding how R works, but could somebody explain why curve(cos(x)) works and curve(expression(cos(x)) does not? I have done some investigating and here is what I found. If I comment out the line of curve indicated below, both calls work fine. function (expr, from, to, n = 101, add = FALSE, type = "l", ylab = NULL, log = NULL, xlim =

I've just committed some fairly big changes to R-devel. - There's a new tag \Sexpr which allows R code to be embedded within the Rd file, similar to Sweave, \RdOpts corresponds to \SweaveOpts. - The parser now mainly issues warnings, rather than errors, in case of syntax errors. It throws away a few tokens and tries to restart. This should let you see most of your errors in

Dear R Developers, the new simplify argument in apply causes that my package (hsdar) does not pass the checks in R-devel. The workaround, Kurt Hornik send me, is working for the R-code: if("simplify" %in% names(formals(base::apply))) do something else do something else Unfortunately, I cannot conditionalize the man pages of the functions. I get the message that

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}

I have problems with very large numbers using knitr. In the following, my a and b are extremely small and ssrr and ssru are extremely large. Knitr delivers error messages. Scaling ssrr and ssru by 1000 resolved the problem: ssrr <-ssrr/1000 ; ssru<-ssru/1000 Any clue as to how I might resolve the problem? BTW, the same program does run in another computer. I am wondering whether my

Hi, Is it possible in Sweave to put \Sexpr{} inside <<>>? This is a bad example, but here goes: <<results=hide>> Age <- 5 @ <<>> x <- \Sexpr{Age} @ I'm trying to get it to display x <- 5, rather than x <- Age. It's probably so obvious I'm going to feel sorry for having to ask, just the same, I'm stumped. Any ideas? Thanks. --
