Code Example 1

# Short answer:
# In R you can completely exit from a loop with "break", or skip to the
#	next iteration of a loop with "next"

# Example of next and break:
for (i in 1:5) {
  if (i == 2) { # Skip to next iteration if i = 2
    next
    }
  if (i == 4) { # Exit loop entirely if i = 4
    break
    }
  print(i)
}
# Returns:
[1] 1
[1] 3

Code Example 2

for (i in 1:10){
 ifelse(i >= 5, break)
}
