Can the R next Statement be used in a while loop?
a) Yes, it can be used to skip the current iteration and proceed to the next
b) No, it is only applicable to for loops
c) Yes, but it only works with numeric conditions
d) No, it cannot be used in a while loop
Answer:
a) Yes, it can be used to skip the current iteration and proceed to the next
Explanation:
The next
statement in R can be used in a while
loop to skip the current iteration and proceed to the next iteration. It is not limited to for
loops and works in any loop where you need to skip certain iterations based on specific conditions.
# Example using next in a while loop
i <- 1
while (i <= 5) {
i <- i + 1
if (i == 3) {
next # Skip when i is 3
}
print(i)
}
# Output:
# [1] 2
# [1] 4
# [1] 5
# [1] 6
In this example, when i
equals 3, the next
statement skips the rest of the loop body and continues with the next iteration, effectively skipping the print statement for that iteration.
