R next Statement

 The next statement is used to skip any remaining statements in the loop and continue executing. In simple words, a next statement is a statement which skips the current iteration of a loop without terminating it. When the next statement is encountered, the R parser skips further evaluation and starts the next iteration of the loop.

This statement is mostly used with for loop and while loop.

Note: In else branch of the if-else statement, the next statement can also be used.

Syntax

There is the following syntax for creating the next statement in R

Flowchart

Example 1: next in repeat loop

1. a <- 1            
2. repeat {          
3.   if(a == 10)    
4.     break    
5.   if(a == 5){    
6.     next       
7.   }    
8.   print(a)    
9.   a <- a+1    
10. }    

Output:

Example 2: next in while loop

1. a<-1    
2. while (a < 10) {    
3.   if(a==5)    
4.     next    
5. print(a)    
6.   a = a + 1    
7. }    

Output:

Example 3: next in for loop

1. x <- 1:10  
2. for (val in x) {  
3. if (val == 3){  
4. next  
5. }  
6. print(val)  
7. }  

Output:

Example 4

1. a1<- c(10L,-11L,12L,-13L,14L,-15L,16L,-17L,18L)  
2. sum<-0  
3. for(i in a1){  
4.     if(i<0){  
5.         next  
6.     }  
7.     sum=sum+i  
8. }  
9. cat("The sum of all positive numbers in array is=",sum)  

Output:

Example 5

1. j<-0  
2. while(j<10){  
3.     if (j==7){  
4.         j=j+1  
5.         next  
6.     }  
7.     cat("\nnumber is =",j)  
8.     j=j+1  
9. }  

Output:
