The `next` statement is used to skip an iteration of a loop. This means that the code block within the loop will not be executed for the current iteration. The `next` statement is often used to skip over iterations that do not meet a certain condition.
For example, the following code will print the numbers from 1 to 100, but it will skip the first 20 iterations:
for (i in 1:100) {
if (i <= 20) {
next
}
print(i)
}
The `break` statement is used to exit a loop immediately. This means that the code block within the loop will not be executed for any subsequent iterations. The `break` statement is often used to exit a loop when a certain condition is met.
For example, the following code will print the numbers from 1 to 100, but it will stop after 20 iterations:
for (i in 1:100) {
print(i)
if (i > 20) {
break
}
}
The `next` and `break` statements are both useful tools for controlling the flow of execution in loops. However, it is important to use them carefully, as they can also be used to create infinite loops.
Note
- The next statement can only be used within a loop.
- The break statement can be used within a loop or outside of a loop.
- The next statement will skip the current iteration of the loop.
- The break statement will exit the loop immediately.
