What is the effect of using the R next Statement inside a for Loop?

a) It skips the current iteration and continues with the next one
b) It exits the loop entirely
c) It pauses the loop until a condition is met
d) It reverses the order of iterations

Answer:

a) It skips the current iteration and continues with the next one

Explanation:

When the next statement is used inside a for loop, it skips the current iteration and continues with the next one. This is useful for bypassing specific values or conditions within the loop without exiting the loop entirely.

# Example of using next in a for loop
for (i in 1:5) {
    if (i == 2 || i == 4) {
        next  # Skip iteration when i is 2 or 4
    }
    print(i)
}

# Output:
# [1] 1
# [1] 3
# [1] 5

In this example, the loop skips printing the values 2 and 4 and continues with the other iterations. The next statement provides a way to handle specific conditions dynamically within the loop.
