breaking out of for loop when running a function inside a for loop in R
- by andrewj
I'm embarrassed that I'm asking this question, but here I go:
Suppose you have the following function foo. When I'm running a for loop, I'd like it to skip the remainder of foo when foo initially returns the value of 0. However, break doesn't work when it's inside a function.
As it's currently written, I get an error message, no loop to break from, jumping to top level.
Any suggestions?
foo <- function(x) {
y <- x-2
if (y==0) {break} # how do I tell the for loop to skip this
z <- y + 100
z
}
for (i in 1:3) {
print(foo(i))
}
