Hi,
	Ever since the G4 came out I've been interested in the potential
for number crunching applications to take advantage of altivec, the G4's
parallel processing unit. It seems like altivec should give the G4 a great
advantage for these kinds of applications, but I've heard that it's not
always the case. For instance, I know that Stata isn't altivec optimized
because Stata works with double precision and altivec is only single
precision. So I'm wondering, do either of the mac versions of R use
altivec?
