How can the R for Loop be combined with the break Statement?

a) To exit the loop prematurely when a certain condition is met

b) To skip every other iteration

c) To reverse the order of iterations

d) To convert the loop into a repeat loop

Answer:

a) To exit the loop prematurely when a certain condition is met

Explanation:

The break statement can be used within a for loop to exit the loop prematurely when a specific condition is met. This allows you to stop further iterations and move on to the next part of your code.

# Example of using break in a for loop
for (i in 1:10) {
    if (i == 4) {
        break  # Exit loop when i equals 4
    }
    print(i)
}

# Output:
# [1] 1
# [1] 2
# [1] 3

In this example, the loop stops when i equals 4, and the remaining iterations are not executed. The break statement is useful for terminating loops early when the desired condition is met.
