R help - Jan 2006 - measuring computation time

Hi R users

Is there any function or command for measureing computation time?

For example, if I like to how long it takes to generate 100000 random 
numbers from a normal

distribution, Is there any command I can wrap up around
"rnorm(100000,0,1)"
and returns time

in a sec unit ?

Thanks

TM

there is

system.time(rnorm(100000,0,1))

RSiteSearch("time") would have told you that
