The CPU time and elapsed time are essentially identical. (That is, the
system time is negligible.)
Using Rprof, I just ran the code twice. The first time, while
randomForest is doing its thing, there are 850 consecutive lines which
read:
".C" "randomForest.default" "randomForest" "randomForest.fo
Are you looking at the CPU or the elapsed time? If it is the elapsed
time, then also capture the CPU time to see if it is different. Also
consider the use of the Rprof function to see where time is being
spent. What else is running on the machine? Are you doing any
paging? What type of system
I am using the randomForest package. I have found that multiple runs
of precisely the same command can generate drastically different run
times. Can anyone with knowledge of this package provide some insight
as to why this would happen and whether there's anything I can do
about it? Here are som
