How much time a process need?
Alaios: Generally I would think you would look at the elapsed field (at least I do): consider the example you ran to give that data. Did it take about half a second or a minute? Gabor showed this example once to illustrate the difference: system.time(Sys.sleep(20)) Michael PS -- If you really want to dig into this, try this set of tools: https://code.google.com/p/rbenchmark/

So I just need to get the ?? user? system elapsed ? 0.460?? 0.048? 67.366 user value and convert the seconds to days and then to hours ? Right? What about this elapsed field?
It's all in seconds. ?Convert whatever fields you want. Josh

I was using system.time(callmyfunction()) to measure how much time it needed to finish, my problem is that I do not know how to interpret their numbers. I was looking to convert these results to something more readably like. "This function took 1 Day 2 hours and 35 minutes to complete." How I can convert the system.time output to something like that? system.time() responds in seconds, hence you can apply simple arithmetic to get days, hours and minutes. Uwe Ligges B.R Alex ???
