[R-SIG-Mac]R-1.4.0 MacOX/Darwin problem

[Jan de Leeuw]

Peter

I do not have any of these problems, all your examples run fine. Could 
you
let ne know what Mac, and what Mac OS X you have ? One thing
I could imagine is that ATLAS uses Altivec instructions for single
operations, which means that these problems may occur CPU's
without Altivec. Maybe others could verify. Also, you do need OS X
version 10.1 at least, I think.
