Feature request: put NewEnvironment and R_NewhashedEnv into API
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

defines in Rmath.h and R_NO_REMAP
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I'm programming with R 2.7.2 and had some trouble including Rmath.h for its random variates generation routines: Although I define R_NO_REMAP (which works fine for Rinternals.h stuff), Rmath.h defines "beta" as "Rf_beta" etc., so that my "beta" strings get redefined as well! Is this a feature? I found an old

undefined symbol: Rf_rownamesgets
I get the error undefined symbol: Rf_rownamesgets when I try to load my package, which include C++ code that calls that function. This is particularly strange since the code also calls Rf_classgets, and it loaded OK with just that. Can anyone tell me what's going on? For the record, I worked around this with the general purpose attribute setting commands and R_RowNamesSymbol. I

How do I access class slots from C?
Hi I'm trying to implement something similar to the following R snippet using C. I seem to have hit the wall on accessing class slots using C. library(fPortfolio) lppData <- 100 * LPP2005.RET[, 1:6] ewSpec <- portfolioSpec() nAssets <- ncol(lppData) setWeights(ewSpec) <- rep(1/nAssets, times = nAssets) ewPortfolio <- feasiblePortfolio( data = lppData, spec = ewSpec,

Calling C++ from R
Hi All, I am new to this area and use Rcpp to call C++ from R and try to build the package under Windows 7. I use Rtools and R 2.10.1 32bit. Everything works fine with me, except using R functions like "rnorm" or "runif" in the C++ code. When I use "R CMD check" the package, it always return error ** libs making DLL ... g++

Looking for protect()
Hello: This is a simple, I hope, question about the first example in section 3.6.4 of the manual, "Writing R extensions." I'm using R 1.1.0, and below I list some easy code that I got from section 3.6.4. When I try to compile the file out.c under NT 4, using VC++ 6.0, I get the following error messages: Compiling... out.c Linking... out.obj : error LNK2001: unresolved external

include <R.h>
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

C/C++ namespaces
Dear community, this is just a suggestion, but might be useful for the following R releases. I was programming some C code for R and my compiler constantly showed me some crazy messages that a stdc++ macro length() was supplied with 4 arguments whereas only one was required. The problem could be partially resolved by changing the order of includes. However as soon as the file was used from

Latent flaw in SEXPREC definition
There seems to be a latent flaw in the definition of struct SEXPREC in Rinternals.h, which likely doesn't cause problems now, but could if the relative sizes of data types changes. The SEXPREC structure contains a union that includes a primsxp, symsxp, etc, but not a vecsxp. However, in allocVector in memory.c, zero-length vectors are allocated using allocSExpNonCons, which appears to

Problems to compile examples of RInside
Hello, I have some problems to migrate to R >3.0 my devel machine (R.2.15.2). So I decided to start from scratch with a brand new virtual machine.

R/C++/memory leaks
Dear all, I have wrapped a C++ function in an R package. I allocate/deallocate memory using C++ 'new' and 'delete'. In order to allow user interrupts without memory leaks I've moved all the delete statements required after an interrupt to a separate C++ function freeMemory(), which is called using on.exit() just before the .C() call. I am concerned about the

Dealing with R list objects in C/C++
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

Problem with Rboolean in c++ code
I am trying to use R_RegisterCFinalizerEx to ensure some c++ object is properly deleted after use. However, I run into some problems when trying to pass in the third argument which is an Rboolean.

Clarifications please.
Hi I think I have asked these questions earlier, but I been able to find answers from the documentation (which I found poorly written in several places). Will someone be kind enough to give me answers and enlighten me? (as in explain with CODE?)
