Re: [R] exit function in R?
Thank everybody for the answers! The stop and quit functions are what I
need (it is a script, not a function what needs to be terminated. I was
talking about an "exit" function, what can be confusing).
Best,
Federico

Re: [R] exit function in R?
Since Frederico indeicated he was running a script, rather than a
function, I suspect that he would be better served by the
quit("no")
function.

Others have suggested using stop(). It might be the case that the
condition not being fulfilled is not actually a sign of an error,
but simply of a different, perhaps ``marginal'' situation in which
a different sort of action or calculation is required. In which
case what you want is return().
Trivial e.g.:
foo <- function(x) {
if(any(x<=0)) return(42)
y <- sum(log(x))
y
}
