Hi, I would like to be able to create new environments from package C code. AFAICT, this isn't allowed since both NewEnvironment and R_NewHashedEnv are declared in Defn.R. If exposing this isn't controvertial, I would submit a patch. However, I'm not sure where the declarations should go (Rdefines.h?) and whether they need to change to Rf_*. + seth

Hi, as Seth Falcon in 2006, I also need to create new environments from package C code. Unfortunately, both NewEnvironment and R_NewHashedEnv are not yet part of the public API, if I understand correctly. Is it planned to add at least one of these functions to the public API in the near future? May I submit a patch? Otherwise I would need to re-implement much of the functionality of R environments in my own code....

nchar(with(list(2),ls())) gives an internal error. This is of course a peculiar call (no names in the list), but the error is not caught cleanly. It is not clear from the documentation whether with(list(2)...) is allowable; if it is not, it should presumably give an error. If it is, then ls shouldn't have problems with the resulting environment. > qq <- with(list(2),ls())

Hi all, I've got a basic question regarding package documentation and rd.sty. I wrote my first own package, and now I would like to place the documentation into the appendix of another LaTex document. Seemingly I cannot simply \usepackage{Rd}, as this will modify the page-settings of my document. Is there a minimum style file which will just define the environments and commands needed for

Hi all, I am using Sweave to produce a document. Unfortunately, I have to print several copies and I can't print them in color. So I would like to change the way of printing the code. I would like to print the code in a box with a black borderline and a grey background (quite classic). Is it possible to do it by changing some Schunk options? Christophe

Is there an elegant way to get Sweave to center graphics by default? I'd like to use \centerline{\includegraphics{}} etc. to save some vertical space that \begin{center} ... \end{center} uses, and I'd like to avoid centering with each <<fig=T>>= Thanks Frank -- Frank E Harrell Jr Professor and Chair School of Medicine Department of

Hi list, I was using Sweave and was wondering if anyone has had any luck changing the font colors of the code chunks. For instance, in my .Rnw preample I tried including: === \usepackage[usenames]{colors} \definecolor{darkred}{rgb}{0.545,0,0} \definecolor{midnightblue}{rgb}{0.098,0.098,0.439} \DefineVerbatimEnvironment{Sinput}{Verbatim}{fontshape=sl,formatcom={\color{midnightblue}}}

Hi! I am currently using Sweave for writing my bachelor thesis - and I have a problem: I am using a LaTeX style (report) with quite big margin spaces. The Sweave generated LaTeX code "floats" into the margin - and it looks ugly. The text is blocked and fine... then there comes some flattering code running over the margin... and blocked text again. Considering the LaTeX output, I guess

I find Sweave very useful and I was trying to combine it with the latex package fancyvrb. I was trying to get line numbering and labels in order to reference the lines where particular commands occur. Unfortunately, I haven't been able to figure out how to do it. Maybe somebody can help me. The following is a sample Rnw file: the first part shows what I would like to get, the second what I

I have data that looks like this: > df1 group id 1 red A 2 red B 3 red C 4 blue D 5 blue E 6 blue F I want a list of the groups containing vectors with the ids. I am avoiding subset(), as it is only recommended for interactive use. Here's what I have so far: df1 <- data.frame(group=c("red", "red", "red", "blue",
