similar to: RH 9 and R 1.7.0 Beta - Errors Resolved

Hi R-devel, I have a question about the differentiation between NA and NaN values as implemented in R. In arithmetic.c, we have int R_IsNA(double x) { if (isnan(x)) { ieee_double y; y.value = x; return (y.word[lw] == 1954); } return 0; } ieee_double is just used for type punning so we can check the final bits and see if they're equal to 1954; if they are, x is NA, if they're

Hello, I notice in main/arithmetic.c, that NA and NaN are encoded differently(since every numeric NA comes from R_NaReal which is defined via ValueOfNA) . What is the benefit of treating these two differently? Why can't NA be a synonym for NaN? Thank you Saptarshi (R-2.9)

Hi everyone, I have been trying to extend Rcpp with my own wrap and as templates. Two issues: 1) I need to explicitly call wrap. Is that expected? So for example I wrote this specialization: template<> SEXP Rcpp::wrap(std::vector<TimedOptDouble> const& entries) { std::vector<double> sec_times; std::vector<double> doubles; for(auto const& entry : entries) {

Hi, This is Kotien Wu from NIH/NCI. We want to use R function for our web: http://cgap.nci.nih.gov It works for functions in R/R-1.9.1/src/nmath/standalone very well. We have function GetPvalueForT.c which has #define MATHLIB_STANDALONE 1 #include <Rmath.h> double GetPvalueForT ( double t, double deg ) { return 2 * pt(t, deg, 0, 0); } We create GetPvalueForT.i, which has /* File :

Hi all, I am now up and running on RH 9. Went pretty smoothly (about 1 hour for the clean install, though still doing some "tweaking".) There are already about 40 update RPMS including a new kernel via RHN, which I have installed. Noticeable improvements since 8.0, especially with the new version of XFree86, which yields sharper fonts that are now (with TTF fonts installed)

In trying to run John Fox's new Rcmdr package on Redhat Linux 9, I got this error message. The problem is in loading the tclck library. library(tcltk) produces the same error. It has been discussed before, e.g., http://finzi.psych.upenn.edu/R/Rhelp02/archive/11898.html but with respect to earlier versions of Linux and R. I tried updating to the latest RPMs of tcl and tk (8.3.5-89), but that

In the maps library, NA's are inserted between polygons so lines() can be used to draw all polygons at once. The code to do it is like this: *x++ = NA_REAL; *y++ = NA_REAL; where x and y are declared as double *x, *y, *range; and are the arguments passed in through a .C call. However, the values show up in R as -6.62314033633867e-229 instead of NA, so the

Hi, I'm trying to install xen+Debian Etch on a Geode LX system. Xen boots fine, but although the package "libc6-xen" is installed I have a large number of such errors: 4gb seg fixup, process syslogd (pid 1878), cs:ip 73:b7f24610 All processes triggers it, and from what I've found on the web it's a sign that libc6-xen is not recognized. Indeed:

Dear R developers, I spotted that R_isNA and R_IsNaN could be improved when applied on a vector where we could take out small part of their logic, run it once, and then reuse inside the loop. I setup tiny plain-C experiment. Taking R_IsNA, R_IsNaN from R's arithmetic.c, and building R_vIsNA and R_vIsNaN accordingly. For double input of size 1e9 (having some NA and NaN) I observed following

I am trying to parallelize part of a C function that is called from R (via .C) using OpenMP's "parallel for" pragma. I get mixed results: some runs finish with no problem, but some lead to R crashing after issuing a long error message involving memory violations. I found this post, which describes how a .Call() function can be made to avoid crashing R by raising the stack limit:

Hello Everyone, After trying several ways to compile R 3.2.2 without luck, I?m reaching out for help.
