Hello Simon thanks for this. [snip]
Yes, I can reproduce it with R 2.4.1 on G5 when using vecLib BLAS. It doesn't crash when using R's BLAS, so that is a work-around. Given that the crash occurs in vecLib and works with with R's BLAS, I'm inclined to think that it's a bug in vecLib, but it will require some more digging to see if that's really the case...
How do I force R to use R's BLAS?
For the CRAN release of R 2.4.1 it is as simple as cd /Library/Frameworks/R.framework/Resources/lib rm libRblas.dylib ln -s libRblas.0.dylib libRblas.dylib to switch back to vecLib, replace the last line with ln -s libRblas.vecLib.dylib libRblas.dylib
*Please* when reporting problems include exact information on the hardware used - there are simply too many different Mac platforms now...
For future reference, how exactly do I do this? "about this Mac" says "Dual 2GHz PowerPC G5, 1.5GB DDR SDRAM" is that what you need or is there a way to get more detailed info?
That is sufficient. Another way is to use sessionInfo() or indeed providing both is the best way. Thanks, Simon
