Dear all,
I have a function f(x).
ptm<- proc.time()
y=f(x)
proc.time() - ptm
works fine for me.
However it is not possible to write
system.time(y=f(x))
and
system.time(f(x))
does not store the value of f(x).
Should I prefer the 3 lines with proc.time ?
No. You should be careful in your use of '=' which is only allowed at
top level.
Try
system.time(y <- f(x))
and see ?"=".

Thank you very much,

?system.time can help too.

Hi,
I want to time how long a function takes to execute. Any clues on what to
search for to achieve this?
Thanks in advance.
