I noted that there is a hsv2rgb in the C-API, but no corresponding function in R, while rgb2hsv is available in R. Does the functionality of hsv2rgb hide under some other name? Dieter

-----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

This is not so much a bug as an infelicity in the code that can easily be fixed. The initialize expression in the quasi family function is, (uniformly for all links and all variance functions): initialize <- expression({ n <- rep.int(1, nobs) mustart <- y + 0.1 * (y == 0) }) This is inappropriate (and often fails) for variance function "mu(1-mu)".

Dear all, I have a problem in calling my C code from R. If I do not need to use #include<R.h>, the codes work properly. But when I need to use it, my codes produce an error as: logpostCLM.cpp:7:15: error: R.h: No such file or directory logpostCLM.cpp:8:24: error: Rinternals.h: No such file or directory logpostCLM.cpp:9:19: error: Rmath.h: No such file or directory logpostCLM.cpp:10:24:

Dear R users, I would like to use several R functions from a C-code and I have read the "Introduction to the .C Interface to R". Unfortunately, my shared library with the C-code works only in cases where I use R-routines that are defined Rmath.h, eg. ************************************* less test.c: #include <R.h> #include <Rinternals.h> #include <Rmath.h> void

Hi, Has anyone encountered the problem of rgamma function in C? The following simplified program always dies for me, and I wonder if anyone can tell me the reason. #include <Rmath.h> #include <time.h> #include <Rinternals.h> SEXP generateGamma () { srand(time(NULL)); return (rgamma(5000,1)); } Has anyone encountered a similar problem before? Is there another way

[The package XML is labelled ORPHANED and a comment says the CRAN team maintains it. I am not sure what address to send this to.] In package XML version 3.98.1.11, RUtils.c registers the C function RS_XML_xmlNodeChildrenReferences twice. The registration information is identical but this could cause maintenance problems if the routine were changed. % grep -n RS_XML_xmlNodeChildrenReferences

Full_Name: David Larsen Version: 1.5.1 OS: Redhat 7.2, w98, w2000 Submission from: (NULL) (128.206.66.65) I have c code that produces vector sequences for plotting. I use NA_REAL to create an NA that will pass back to R to break the line. This code worked fine upto R-1.5.0 It continues to work on Redhat7.2 Linux but on both windows98 and windows2000 the NA_REAL returns -6.623485e-229 on both

Dear All, I have been trying to compile a package for windows that we have written. Since R version 3.0.0 the package doesn't compile any more. (On Linux the package compiles without errors).

Hi, I get an "Conditional jump or move depends on uninitialised value(s)" from valgrind when using 'solve' in combination with some simple C-code. (I did not use other functions of R besides 'solve'.) In detail: running R --vanilla -d "valgrind --tool=memcheck --memcheck:leak-check=yes --num-callers=20 " and calling .Call("XXX") nd <- 3

Hi all, I have a problem but i am not sure that this is the right mailing list. I'm writing a R program which call a C++ program, through the function .Call. I use to compile the c++ script with the command R CMD SHLIB SpTempWrapC.cpp -Wall -l covmodel.h -l util.h Everything works fine since, for mistake, i paste in the terminal the content of the r-script. Now, when i try to compile,

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++

Dear R experts, I'm trying to call 'pchisq' from within a C subroutine. The following error is returned: ** NON-convergence in pgamma()'s pd_lower_cf() f= nan. This error message is not printed the first time I call 'pchisq' from the C subroutine, but the second time or the next time I call 'pchisq' from within R. My session output is shown below:

Hello, I'm having some difficulty to understand how I could take the proper result from the following listing: -- cut --- #include <stdlib.h> #include <R.h> #include <Rmath.h> void retMat ( double **y, int *n, int *m, double *a, double *b) { int i, j; y = malloc( (*n) * sizeof( double ) ); for (i=0; i<*n; i++) { y[i] = malloc (

I tend to use table() quite a bit for quick "diagnostics", summary, etc. I have wished for a more automatic way of plotting these. One possibility would be something like the following function; The question is if (something like) the following is worth providing (and then maintaining...) at all : plot.table <- function(x, type = "h", ylim = c(0, max(x)), lwd = 2,
