*when do you get kicked out of a while loop?*
(i.e., in the following example what would the final value of 'a' be?) i
thought it would be 99 but running it in R i get 101 (and 101 for x too!)
while (x <100) {
for (i in 1:101) {
i -> x
x -> a
}
}
If you are trying to jump out of a for loop early then try something like:
for (i in 1:101) {
i -> x
if (! x<100 ) { break }
x -> a
}
the "next" command will also skip the rest of the body of the loop and
start on the next iteration.
Hope this helps,
