Hi all, Since proc.time return three different kind of times (user, system and elapsed) , I am wondering which one is right for calculating flops. In New S Language (Becker et. al. ) , it seems to be the user because " the user time measures the processor time used in S and the system time measures the operating system in response to S's request". But in R Help , system time sounds better as " The first two entries(referred to user and system time respectively) are the total user and system CPU times of the current R process and any child processes on which it has waited". Please help . Thanks.
