similar to: R CMD check linking errors, when interfacing c++

Hi there, I am trying to interface c++ code in R and make a package. With R CMD SHLIB the dll was created, but when I try R CMD check, I am getting 'undefined reference to..' linkage error messages. The relevant c++ source from conf-infomap.cpp: #include "conf-infomap.h" #include "R.h" // R functions #include "Rinternals.h" #include "Rmath.h" //

First: Im sorry for my bad english ;-) I use "portfolio" to create treemaps with "R". I've got a .csv dataset of all the schools in my city, containing 6 variables each with 1469 lines of data. When I create a treemap, 3 of these schools were not taken into account by "R". I dont know why. It doesn't matter where I put them in my dataset, they won't

Hi all, I am running R 2.5.0 under Windows XP Media Center Edition. Here's a problem that's been stumping me for a few days now, and I can't find anything useful in the archives. I am using voronoi.mosaic (tripack package) to create proximity polygons for a study of vegetation competition and dynamics. The points lists are read in from a file for each plot, then 8 duplicates

Has anyone implemented "treemaps" in R? A "treemap" is a visual display of a tree structure in which, at each level, the several nodes are represented by rectangles which fill the available area. The areas of the rectangles represent size, and their colors represent some other variable. There are several algorithms for deciding how to place the rectangles, ref:

Let's say I have data in the following schema that describes the number of purchases a company has received from each County in the US: State | County | Purchases --------------------------------------- NJ | Mercer | 550 CA | Orange | 23 .... I would like to visualize what states contribute the most to the overall total, and furthermore within those states, what Counties contribute the most.

A ZFS file system reports 1007GB beeing used (df -h / zfs list). When doing a ''du -sh'' on the filesystem root, I only get appr. 300GB which is the correct size. The file system became full during Christmas and I increased the quota from 1 to 1.5 to 2TB and then decreased to 1.5TB. No reservations. Files and processes that filled up the file systems have been removed/stopped.

Hi~I'm new to R. I'm following these two tutorials to make a tree map, but the color scale isn't quite what I wanted. For map of the market, the color scale starts from 0(red) to max(green), what I wanted is 0(Green)-1(Red)-max(green). What's the easiest way to achieve this kind of divergent color scale? How shall I make my own palette and use it in the map.market or tree map

Dear all As far as I could trace, looking at the function C function numeric_deriv, this unwanted behavior comes from the inner most loop in, at the very end of the function, for(i = 0, start = 0; i < LENGTH(theta); i++) { for(j = 0; j < LENGTH(VECTOR_ELT(pars, i)); j++, start += LENGTH(ans)) { SEXP ans_del; double origPar, xx, delta; origPar = REAL(VECTOR_ELT(pars, i))[j];

Hello: I've been trying for days now to get igraph working on a debian sarge install. There does not appear to be any pre-built packages, and when I try and install within R, it blows up on the final linking, claiming its unable to find libgfortran (which IS installed, and IS working for all other users of the compiler). I started up R and ran: install.packages("igraph"). It

I get a segfault when trying to read a SAS transport file with rather long rows using read.xport from package foreign (version 0.4-7). The culprit seems to be these lines in xport_read in SASxport.c: 590 } else { 591 c = strchr(tmpchar, ' '); 592 *c = '\0'; 593

Dear All, we have released version 0.6 of the igraph package today. This is a major new version, with a lot of new features, and (sadly) it is not completely compatible with code that was written for the previous igraph versions. (See "Major new features" below for details.) I have included below a list of (bigger) changes. Please see the details in the release notes and the NEWS

Hi all I don't know if my message are correct in this forums. I create a program in c++ who use statistical function. I want to execute this function in R (in particular for use packages ade4, lattice, bioconductor...) Until now, my program work for simple function ("plot", "rnorm"...) but I can't use library My class are : // in constructor int argc = 1;

First, thanks to those of you who responded to my previous post about my code that was taking longer and longer to process. After following your suggestions, and I now thinking that the problem was some calls to Rf_duplicate in my C code. So I'm hoping I could get some clarification on what Rf_duplicate actually does. What is the real difference between PROTECT(y=x); and PROTECT (y =

Hello Aidan, Sorry for dropping this for a while. ?

If you do end up using eval(), it may make sense to move lang3() out of the loop and reuse the existing object

Can someone lend me a hand with extracting the dimnames from a SEXP? I've looked through R-exts, but I couldn't find an example. Here is the code I'm using to grab the jth column name and print it, but the colnames I'm getting are garbage. None of the following are working. void printInfo(SEXP ts) { int j; for (j=0; j<col; j++) {

Hello at all ! What is the correct form to give a list form R (e.g. list(c(-1,1), "TestFile") ) to C. I have no problems, if I don't use character and I have also no problems to give a character vector form R to C. But, if I combine real and strings in a list then I don't know the correct syntax. I try it with following (an example): SEXP writeFile(SEXP headerR){ Image

I'm new to R development, so this may be a trivial question. In C, How do you convert a SEXP value returned by an R function to a primitive C type (int, double, char, array, etc.)? I've tried using the INTEGER(x), VECTOR_ELT(x,i), and similar functions found in /src/ include/Rinternals.h, but doing so results in incorrect results or a seg-fault. For example, I modified

Hello, I create a VECSXP(call it A) with size N(~ 5000), i then proceed to fill the elements and find out I don't need to fill more than M (M<< N). Thus if i return A to the user's R code, he/she will see a list of length 5K of which N-M are NULLs. To avoid this, I create a new VECSXP B of length M and /duplicate/ the elements of A. Since I do this often, it appears to be wasteful,
