Hi, Again, sorry for the length of this post. Once I get my new office I will get a website set up on my work machine and will simply post a link to the log since I doubt many people are truly interested in these logs. To further analyze what is happening, I added my own routine in main.c called DEBUG_SET_NAMED and then redefined the SET_NAMED macro to use it and then rebuilt R. I

Dear R-Developers, I just started learning how to use Rcpp. Earlier while using it, I encountered an error as shown below: file74d8254b96d4.cpp: In function ‘Rcpp::NumericVector foo(Rcpp::NumericVector, Rcpp::NumericVector, Rcpp::NumericVector, Rcpp::Function, Rcpp::Function)’: file74d8254b96d4.cpp:10: error: invalid operands of types ‘SEXPREC*’ and ‘R_len_t’ to binary ‘operator/’ make: ***

Hello, For the BUILTINSXP and SPECIALSXP types, the R Internals page documents "An integer giving the offset into the table of primitives/.Internals. " What macro gives me the value of this integer? I guess something like this would work had R_USEINTERNALS been defined v->u.primsxp.offset (where v is a SEXP of either of the above types). What is the portable version? Thank you

Hi, everyone. I'm trying to debug an R-module, written in C, and I'm using gdb for this. How can I print "standard" R objects from within C code? BTW, I'm familiar with the advice to use R_PV given in Writing R Extensions, but it's not working for me. E.g., I get (gdb) p R_PV(x) $1 = void and yet (gdb) p *x $2 = {sxpinfo = {type = 16, obj = 0, named = 0, gp = 0,

Hello, I've noticed that with g++ 4.3 I get the following "warning: deprecated conversion from string constant to ?char*?" when I call e.g., Rprintf("Hello world"); or when I try to define a const char e.g., char lower = 'L'; I am wrapping the c++ code in extern "C" {}. This seems to be something new with g++ 4.3, because the same code compiled

Hi folks, I apologise if this is in the documentation somewhere, but I can't seem to find it. I also did a search of CRAN without any success. I'm using R-1.8.1 (pre-compiled) on Windows 2000 with Rtools and mingw 2.0.0 (which includes gcc/g++ 3.2). I'm trying to link some C++ code from another application to R using the .Call interface and am experiencing some problems. I was

Hi, With the sid package jags (2.0.0-1) and r-base-core (2.11.0-1), I cannot install package rjags anymore (this used to work at some point; can't recall exactly at what R/JAGS versions): ---<--------------------cut here---------------start------------------->--- R> install.packages("rjags", configure.args="--with-jags-modules=/usr/lib/JAGS/modules-2.0.0")

I am grateful for the advice of Douglas Bates on my earlier problem in making R-0.62.1, but I'm afraid I'm still having problems.... I have been installing the various updates to R for quite some time on my alpha, and it is only now that I have been having really severe problems. The three or 4 versions before 0.61.1 installed without error. For 0.61.1 I needed to install GNU make. For

I have a use case where I would like to create an SEXP around an existing buffer that is managed by R, thus avoiding a copy operation. If I have something like: void *p = (void*) RAW(PROTECT(Rf_allocVector(RAWSXP, n))); ... additional maniupulation ... SEXP x = somefunc(SXPTYPE, n, p); // ???? Is there a "placement" constructor available? (I have arranged for the corresponding

Hi All, Well I finally have found the time to get svn working and I have successfully built my own tuned atlas (multi-threaded version) libs and have both the r-devel and r-patched trees building daily on my box. The problem is I still do not have a good idea of the layout and design of R, and typically I "learn by doing" by trying to fix a bug that hits me. Unfortunately ;-)

Hi everybody, I''m using R on a 64-bit Ubuntu 9.04 (Jaunty). I prefer to install R packages from source, even if they are available in Synaptic. The problem is that I can''t install/compile kernlab. Everything works fine until it gets to the lazy loading part: ** preparing package for lazy loading Creating a new generic function for "terms" in "kernlab"

Dear list, I am writing C code to interface with R, and I would like to know the level of mutability for the type of a SEXP. I see that there is a macro/function TYPEOF(), and that it can be used as an l-value, as well as a macro/function SET_TYPEOF(). My question is "should the type be considered immutable, or it can it change after the SEXP has been created and used for a while ?".

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++

Hi, I'm quite knew in R, so I might not have the R specific jargon. But here is my problem, I'm trying to access and use variabels given by a function environment, more specifically the rho in do_optim in src/main/optim.c According to the documentation http://cran.r-project.org/doc/manuals/R-ints.html#The-_0027data_0027 the envsxp is defined as a tagged pairlist.

I am running into a wall getting my system to work with rcpp and inline. Following Dirk's advice on stackoverflow, I hope someone is able to help me. My steps were to install MinGW 32 bit first, then installing Rtools, I disabled MinGW's entry in the PATH. I am trying to get the following code to work: library(Rcpp) library(inline) body <- ' NumericVector xx(x); return wrap(

Hi, Please see below for post on r-help regarding data.frame() and the possibility of dropping rownames, for space and time reasons. I've made some changes, attached, and it seems to be working well. I see the expected space (90% saved) and time (10 times faster) savings. There are no doubt some bugs, and needs more work and testing, but I thought I would post first at this stage. Could some
