Need to buy fast computer for running R on. Today we use 2,8 MHz intel D cpu and the calculations takes around 15 days. Is it possible to get the same calculations down to minutes/hours by only changing the hardware? Should I go for an really fast dual 32 bit cpu and run R over linux or xp or go for an quad core / 64 bit cpu? Is it effective to run R on 64 bit (and problem free

When I try to apply mean to a list, I get the answer : argument is not numeric or logical: returning NA Could you help me? (I am a very beginner) -- View this message in context: http://r.789695.n4.nabble.com/mean-tp4674999.html Sent from the R help mailing list archive at Nabble.com.

This series consists of improvements to Xen''s ability to print traces of its own stack, and specifically for the stack overflow case to be able to use frame pointers in a debug build. I have dev tested the series in debug and non-debug cases, with and without memory guards, and I believe that all the stack traces look correct (given the available information Xen has), and that the

Enable cpufreq support in Xen for AMD Operton processors by: 1) Allowing the PowerNow! driver in dom0 to write to the PowerNow! MSRs. 2) Adding the cpufreq notifier chain to time-xen.c in dom0. On a frequency change, a platform hypercall is performed to scale the frequency multiplier in the hypervisor. 3) Adding a platform hypercall to the hypervisor the scale the frequency multiplier and reset
