How does the R break Statement control loop execution?

a) It immediately stops the loop and moves control to the next statement after the loop

b) It pauses the loop until a condition is met

c) It restarts the loop from the beginning

d) It continues the loop but reverses the iteration order

Answer:

a) It immediately stops the loop and moves control to the next statement after the loop

Explanation:

The break statement in R is used to immediately stop the loop and move control to the next statement following the loop. It provides a way to exit the loop early when a specific condition is met, allowing for more efficient and controlled execution of the loop.

# Example using break to exit a loop
for (i in 1:5) {
    if (i == 3) {
        break  # Exit loop when i equals 3
    }
    print(i)
}

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

In this example, the loop terminates when i equals 3, and the remaining iterations are not executed. The break statement is a powerful tool for controlling loop execution, allowing for early termination based on dynamic conditions.
