similar to: Feature request: put NewEnvironment and R_NewhashedEnv into API

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

Dear developers, is it possible to create environments in C code of packages? Simply using SEXP env; PROTECT (env = allocSExp(ENVSXP)); and assigning the enclosing environment with SET_ENCLOS seems to be insufficient.

Hi all, I really like the addition of `R_NewEnv()` back in 4.1.0 https://github.com/wch/r-source/blob/625ab8d45f86f65561e53627e1f0c220bdc5f752/src/main/envir.c#L3619-L3630 I have a use case where I'm likely to call this function a large number of times to generate many small hashed environments, so I'd like to optimize it as far as possible. I noticed that it takes `int size`, converts

Hi all, I've noticed some peculiarities in the tools:::funAPI output that complicate its programmatic use a bit. - Is it for remapped symbol names (with Rf_ or the Fortran underscore), or for unmapped names (without Rf_ or the underscore)? I see that the functions marked in WRE are almost all (except Rf_installChar and Rf_installTrChar) unmapped. This makes a lot of sense because some

I am attempting to bring R-3.0.2 functionality into a project with a very large C++ codebase. The existing codebase already has a LENGTH function defined. R also defines a LENGTH function. I first compiled R as a shared library and linked it into this existing codebase, along with RInside. When I run a parseEvalQ with a linear model command it will stack dump. Looking at the backtrace, what is

Hello Folks, When I run the document below through sweave, rgui.exe/rsession.exe leaves a file handle open to the sweave-001.pdf graphic (as verified by process explorer). Pdflatex.exe then crashes (with a Permission Denied error) because the graphic file is locked. This only seems to happen when there is an error in the sweave document. When there are no errors, no file handles are left open.

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())

I downloaded current version of FLAC sources and compiled it with: * GCC 4.8.1 (MSYS from http://xhmikosr.1f0.de/tools/) * Intel C++ Composer XE 2013 update 5 * MSVS 2010 SP1 * MSVS 2012 update 3 (SSSE3 and SSE4.1 code was disabled for all compilers) Stereo 24-bit WAV file was encoded with -8 preset.

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

I am trying to add #include <R.h> to a .c file in one of my package, so I can call error() without a complaint about implicit defined function. The src/ has a Makefile, to build some exec/ files that are needed. Without the include, my Makefile target OBJS = $(SRC:.c=.o) $(PKGNAME).so: $(OBJS) rpcx.h $(R_HOME)/bin/R CMD SHLIB $(OBJS) seems to work fine, and I do not need a target

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 Ivan Can you please clarify what input files should be used with your proposed function? I tried a few files in r-svn/src/include and one of them gave me an error. > getdecl("~/R/r-svn/src/include/R.h") [1] "R_FlushConsole" "R_ProcessEvents" "R_WaitEvent" > getdecl("~/R/r-svn/src/include/Rdefines.h") Error in regmatches(lines,

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

Dear Colleagues: In an attempt to have things like # See page \pageref{this} inside comments in R code chunks I have modified Sweave.sty as below. I have followed fancyvrb's manual with regard to the use of the commandchars argument. But when compiling with LaTeX (using attached test file) I get a LaTeX error (/usr/share/texmf-texlive/tex/latex/ae/t1aett.fd) ! Missing \endcsname

Hello R Core team, As someone who working on bindings to the API, having an index of the public API is a very welcome change. In order to improve the ability for users to explore the API, I would like to propose adding a section of the API Index by category. You already have the functions and variables categorized by section, so I would suggest to use sections as the categories, and inside
