I am attaching a patch to R-0.63's configure.in file which will enable R to detect and use some special math libraries on linuxppc and mklinux. The patch provides tests for these libraries and enable/disable switches for them as well. One library is the libmoto math library which must be used in conjunction with libm (it only replaces some of libm's functions). The other is a RISC optimized BLAS library, libblas_risc, which must be used along with a standard implementation of BLAS, libblas. It only provides optimized versions of GEMM routines for s...

...that be bad?) is a hardware-specific issue. is there any store of R-knowledge on what hardware is affected (i'm running on ppc -- the gcc info page mentions m68k and x86) and what, if any, other routines might be affected? along the same lines, is there an official R-stance on the accuracy of libmoto for ppc? i remember having heard some vague mention on a ppc newsgroup about the routines in libmoto being fast but not very accurate. at one point, i compared results from R with libmoto to something else and didn't find anything shocking. thanks for any info. - peter -.-.-.-.-.-.-.-.-.-.-...
