R – Next Statement

Next statement in R is used to skip any remaining statements in the loop and continue the execution of the program. In other words, it is a statement that skips the current iteration without loop termination. 

‘next’ is a loop control statement just like the break statement. But ‘next’ statement works opposite to that of break statement, instead of terminating the loop, it forces to execute the next iteration of the loop.

Next Statement in R Language Example 

Example 1: Using next in the for loop 

R

# R program to illustrate next in for loop

val <- 6:11

# Loop
for (i in val)
{
    if (i == 8)
    {
        # test expression
        next
    }
    print(i)
}

Output:

[1] 6
[1] 7
[1] 9
[1] 10
[1] 11

The next statement can be used with any other loop also like ‘while’ or ‘repeat’ loop in a similar way as it is used with for loop above.

Example 2: Using next in the while loop 

R

# R program to illustrate next in while loop

val <- 6
i = 11
# Loop
while(i>val)
{
    if (i == 8)
    {
        # test expression
        next
    }
    print(i)
    i = i - 1
}

Output:

[1] 11
[1] 10
[1] 9

Example 3: Using next in the repeat loop 

R

# R program to illustrate next in repeat loop

i = 0

# Loop
repeat
{

  if(i == 10)
    break

  if(i == 5)
  {
    next
  }
    print(i)
    i = i + 1
}

Output:

[1] 0
[1] 1
[1] 2
[1] 3
[1] 4
