[R] Time out for a R Function

[Santosh Srinivas]

Thank you.

I tried this but not sure if I have implemented this correctly ... basically
if function1 hangs .. I need the timeout to be triggered and then the
process moves to the next function call.

I have this:

function1 <- function(x){
setTimeLimit(elapsed = 5*60, transient = FALSE)
step 1
step 2
step 3
}


#Code to execute about function repeatedly. It moves to a new input variable
when I call it back through a parameter

repeat{
	function1(x)
}

See the help on setTimeLimit(transient = FALSE) .  Unlike other 
suggestions, that does not need you to change the code to check the 
time.
