How do I time the running duration of R scripts?

I basically want an equivalent to the bash command time.

If it's a complicated script that can't be evaluated by system.time(), try:

start_time = proc.time()
<your script here>
end_time = proc.time()
print(end_time - start_time)

Obviously you need to run lines 1-3 as close to each other as possible.

There are some examples here.

Use system.time, or take a look at the microbenchmark package.
