How to jump to next top level loop?

Question

I have a for loop nested in another for loop. How can I make it so that when somethign happens in the inner loop, we exit and jump to the next iteratio

Answer 1

I think you want to use break so R will stop looping through your inner for loop, hence proceed to the next iteration of your outer for loop:

for (i in 1:10) {
   for (j in 1:10) {
      if ((i+j) > 5) {
         # stop looping over j
         break
      } else {
         # do something
         cat(sprintf("i=%d, j=%d\n", i, j))
      }
   }
}
# i=1, j=1
# i=1, j=2
# i=1, j=3
# i=1, j=4
# i=2, j=1
# i=2, j=2
# i=2, j=3
# i=3, j=1
# i=3, j=2
# i=4, j=1
