R help - Jul 2001 - Summary of variations in how long commands take

Thanks to Guido Masarotto, Brain Ripley and Andy Liaw for (remarkably) quick
answers to my (stupid!) question. As all three noted, I should be using
system.time() instead of proc.time().

Andy also noted that he used constructions like:

my.f <- function(x) {
start <- proc.time()
[some steps]
now <- proc.time()
cat("first step took ",now-start," seconds.\n")
etc.
}

to examine timing within a given function. 

Thanks again for a marvelous program. 

Regards,

Dave Kane
