Hello, I was trying to install Rggobi in the latest version of R and it gave me a compilation error for R CMD INSTALL Rggobi_1.0-0.tar.gz RSGGobi.C: In function RS_GGOBI_init (R_IsNaNorNA) undeclared (line 77) I searched for this function in R src files and it was abandoned in ~/R-2.0.0/src/include/R_ext/Arith.h file. Only functions int R_IsNA(double); /* True for R's NA only */ int R_IsNaN(double); /* True for special NaN, *not* for NA */ are declared leavin...

...ns can be called from from C++ programs, and the API includes the special values ISNAN() and R_FINITE() and the missing test ISNA(). R_FINITE is no problem. It is defined as R_finite, which is declared in Rmath.h and included in libRmath. ISNAN() however is broken. In R 1.9 it was defined as R_IsNaNorNA unless IEEE_754 was defined which was not done in the standalone libRmath/Rmath.h. R_IsNaNorNA was declared in Rmath and included in libRmath. So it would work, although probably not when built against an installed R library because R.h would likely define IEEE_754. In R2.0 ISNAN() is define...

I have a problem building an extension using ISNAN() on R version 2.0.x. In R 1.9.1 Arith.h and Rmath.h contained code like #ifdef IEEE_754 # define ISNAN(x) (isnan(x)!=0) #else # define ISNAN(x) R_IsNaNorNA(x) #endif #define R_FINITE(x) R_finite(x) int R_IsNaNorNA(double); int R_finite(double); which works. R 2.0.x has # define ISNAN(x) (isnan(x)!=0) unconditionally. This breaks because on MacOS X in /usr/include/architecture/ppc/math.h isnan() is itself a macro thus: #define isnan( x )...

...in features to improve performance are: application registers, predication, branching and register rotation. The implication is the cost of disrupting the pipeline is magnified greatly on this architecture. In R, there are quite some simple functions that are called extremely often, such as "R_IsNaNorNA", "R_finite", etc. They are used in heavy loops quite a lot. They disrupt the pipelining, and negatively affect the performance of the software. For instance, on IA64, system call of "isnan" cost 4 cycles, while a wrapper like "R_IsNaNorNA" could cost several t...
