similar to: bug in Rf_PrintValue ?

Hi, I think this is a bug (even though I can't find documentation explicitly saying that it should work). Basically, Rf_PrintValue(obj) fails when 'obj' is an S4 object that should be printed using show() rather than print(). From the error message I'm guessing that the need to use show is detected correctly but then show is not found. "cbind2" in the code below is just

Dear list, While trying to identify the root of a problem I am having with garbage collected variables, I have come across the following oddity: depending on whether --verbose is set or not, I obtain different results. I have made a small standalone example to demonstrate it. The example is very artificial, but I had a hard time reproducing reliably the problem. So when I do: (the content of

Consider the following simple C program: /*** hello_r.c ***/ #include <Rinternals.h> SEXP hello() { return mkString("Hello, world!\n"); } int main(void) { SEXP x = hello(); return x == NULL; /* i.e. 0 on success */ } This program segfaults: % myR/bin/R CMD LINK gcc -I./R-2.9.0/src/include -L./myR/lib64/R/lib -lR hello_r.c -o hello_r > /dev/null % hello_r zsh:

Hi all, im triyng to implement a bayesian model with R and c++. I have a strange problem. I can't reproduce the error with a small script and then i post the original one. The problem is after the line for(MCMC_iter2=0;MCMC_iter2<thin;MCMC_iter2++) For the first 34 iterations all work fine, after, all the simulations of mu_acc_P return an "nan". If i delete the line

Dear friends, I am trying to create a web application to produce some statistical result using R. In order to avoid high CPU usage of web server caused by R, I have to create an ASP.NET web service in another server to involve R. But I am facing the unauthorizedAccessException when I call the web service, even I have assigned access and launch permission to everyone using

Hello, I created a library for a bunch of functions that I use frequently so that I dont have to carry duplicate copies around to wherever I fire up an R sesssion. However, I have problems locating the help files for those functions. Here are some details. I created the library "myR" and installed this in /home/royle/R using: R INSTALL -l /home/royle/R /home/royle/Rpackages/myR

Dear r-devel list members, It's been several years since I last built a custom Windows installer for R, and despite my notes and the instructions in Sections 3.1.7 and D.4 of the R Installation and Administration Manual, I've run into a problem, receiving the following error message: ----------- snip ----------- C:\R\src\R-2.11.1\src\gnuwin32\installer>make myR

Hello, I am trying to compile some F77 subroutines as shared objects for R on my Mac. --> Mac OS-X Version 10.4.11 (Tiger Intel Mac) I have done this (successfully) before on Sun Solaris and Linux Fedora systems using the following command. > R CMD SHLIB myfile.f I have g77 installed from this page. http://hpc.sourceforge.net/ I am using R 2.8.1, and I have installed all 4 additional

Dear R-help list users, I have a huge vector of numbers, how I can invert orden? For example x <- 1:10000000 I would like to obtain x_r <- 10000000:1 Thanks, Sebastian.

I also have several packages in my RW0633 in Windoze and I would like to keep them in one place when I update the R system. Brian say to modify Rprofile to ..lib.loc <- c("c:/MyR/library",.Library) now Rprofile has a line like .lib.loc <- unique(c(unlist(strsplit(getenv("RLIBS"),":")),.Library) Sorry to be dense but where should I put the

Hi, I want to read a text file into R with .Call(). So I define some NEW_CHARACTER() to store the chracters read and use SET_STRING_ELT to fill the elements. e.g. PROTECT(qNames = NEW_CHARACTER(10000)); char *foo; // This foo holds the string I want. while(foo = readLine(FN)){ SET_STRING_ELT(qNames, i, mkChar(foo))); } In this way, I can get the desired character from qNames. The only problem

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?) I want to embed R in my application and use the fPortfolio package for carrying out risk management computations. Right now I'm reading the Rmetrics

I am attempting to build a customized R installer on Windows, using the Inno Setup installer. I am following the instructions in Section 3.1.8 of the R Installation and Administration Manual ("Building the Inno Setup installer"), which includes the following passage: An alternative way to customize the installer starting with a binary distribution is to first make a full

Hi, To speed up reading of large (few million lines) CSV files I am writing custom read functions (in C). By timing various approaches I figured out that one of the bottlenecks in reading character fields is the mkChar() function which on each call incurs a lot of garbage-collection-related overhead. I wonder if there is a "vectorized" version of mkChar, say mkChar2(char **, int

Hi the list, Some rumour (!) say that is it possible to prepare some tests for checking our code using .Rin and .Rout. It seems to be a very good practice, but I did not manage to find information on it. So does someone know how it works ? What are we suppose to write in Rin ? More precisely : - I have a package myPack.r in directories ~/myR/myPack/R/ - I create the directory

Hi everyone. I'm trying to learn my way around the R internals. I've gone pretty much as far as I can go with the information given in Writing R Extensions and R Internals, but I still have a lot of questions, too many in fact to post them to the r-devel list. But I think I could answer many of these if I could just step through R's execution during some basic operations. What

I'm trying to generate an R interface for a library that's commonly used and I'm currently writing wrapper functions for file i/o and return an object (list?) that contains the elements of the C structure. For example, reading a file that contains: struct CONFIG_RECORD { char coeffs_filename[256]; char species_filename[256]; unsigned long

Hi all, I am working with some large data sets (1-4 GB) and have some questions that I hope someone can help me with: 1. Is there a way to turn off garbage collector from within C interface ? what I am trying to do is suck data from mysql (using my own C functions) and I see that allocating each column (with about 1-4 million items) takes between 0.5 and 1 seconds. My

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,
