When should the R next Statement be used inside a while Loop?

a) When you want to skip the current iteration and continue with the next

b) When you want to exit the loop early

c) When you want to pause the loop temporarily

d) When you want to reset the loop variables

Answer:

a) When you want to skip the current iteration and continue with the next

Explanation:

The next statement inside a while loop should be used when you want to skip the current iteration and continue with the next iteration. This is useful when you need to bypass certain conditions or values without exiting the loop entirely.

# Example using next in a while loop
i <- 1

while (i <= 5) {
    i <- i + 1
    if (i == 3) {
        next  # Skip iteration when i is 3
    }
    print(i)
}

# Output:
# [1] 2
# [1] 4
# [1] 5
# [1] 6

In this example, the loop skips printing the value 3 and continues with the next iteration. The next statement allows for more granular control of loop execution, enabling specific conditions to be bypassed.
