R Next Statement

The R Next statement is one of the most useful statement to controls the flow of R loops. We generally use this statement inside the For Loop and While Loop. While executing these loops, if compiler find the Next statement inside them, it will stop the current loop iteration and starts the new iteration from the beginning.

For example, If we have 10 statements inside the loop and we want to skip executing second 5 statements (statement 6 — statement 10) when certain condition is True otherwise, it has to execute all the 10 statements inside the loop. In this situation we place the If Statement with certain condition and within the if block place the Next statement. If the condition is True, compiler will stop executing statement 6 to 10 otherwise, it will execute statements 1 to 10.

R Next Statement Syntax

The syntax of the Next Statement in R Programming language is as shown below:

In this article, We would like to share 2 examples to display the working functionality of the Next statement in both While Loop and For Loop.

R Next Statement in For Loop

In this program we will show you, How to use Next Statement inside the For Loop with example. This program will display the Even and Odd numbers inside the given range.

R CODE

OUTPUT

ANALYSIS

• In this example, we are not going to explain the for loop. If you don’t understand for loop then please visit our article R For Loop.
• Inside the for loop we placed If Statement to test whether (val %% 2 != 0).
  • If this expression result is True then Next statement will be executed and the iteration will stop at that number without printing the other statement: print(paste(“EVEN Number = “, val))
  • If the expression result is false then it will skip the Next statement and prints that number as output (In Our case Even Number)

Next Statement in R While Loop Example

In this program we will show you, How to use Next Statement inside the While Loop with example. This program allows the user to enter any integer values and then it will display all the values from 0 to given number except 4 and 7.

R CODE

OUTPUT

ANALYSIS

Here we are not going to explain the While loop. If you don’t understand While loop then please visit our article While Loop. Inside the While loop we placed If Statement to test whether i is equal to 4 or 7.

• If this condition is True then Next statement will be executed and the iteration will stop at that number without printing the other statement: print(paste(“Values are :  “, number)). For better understanding, we placed print(paste(“Skipped by the Next Statement =  “, number)) inside the If condition. So, whenever the iteration break, that value be printed from this statement.
• If the condition is false then it will skip the next statement and prints that number as output (In Our case 0,1,2,3,5,6,8,9, 10)
