...led us to the conclusion that there are optimization problems with the current gcc in RH 9, which is: gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5) We confirmed this running ./configure CFLAGS="-O0 -g" and I was able to run make check without errors. Bottom line, it appears that R_NaReal was not being set properly. It would take the value of nan(0x8000000000000) instead of nan(0x80000000007a2). This is set in R_NaReal = R_ValueOfNA(). The present version in arithmetic.c is: 117 static double R_ValueOfNA(void) 118 { 119 ieee_double x; 120 x.word[hw] = 0x7ff00000;...

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)

...nd a system with HAVE_FINITE and FINITE_BROKEN defined, then R will not work correctly (unless it uses the AIX workaround). The fix I suggested to Ralf worked, and will probably be incorporated in 0.65.1 (unless we find a better one). Try replacing the line # define R_FINITE(x) ((x) != R_NaReal) in Arith.h by static int R_FINITE(double x) { return !isnan(x) & (x != R_PosInf) & (x != R_NegInf); } -- Brian D.

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

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, I installed the new release 0.65.0 of R on our local Solaris system. As I already (and sucessfully) installed the 0.64.0 and 0.64.1 version of R, I hadn't had any trouble during the installation. But as I've started R in order to see the demo I've got horizontal and vertical lines goint to the left and top of the X11 window at each tick (demo ("graphics")). This seems
