R - next statement

The next statement in R programming language is useful when we want to skip the current iteration of a loop without terminating it. On encountering next, the R parser skips further evaluation and starts next iteration of the loop.

Syntax

The basic syntax for creating a next statement in R is −

next

Example

v <- LETTERS[1:6]
for ( i in v) {
   
   if (i == "D") {
      next
   }
   print(i)
}

When the above code is compiled and executed, it produces the following result −

[1] "A"
[1] "B"
[1] "C"
[1] "E"
[1] "F"

Example - Using next statement in while loop

x <- 10
while(x < 20) {     
   x <- x + 1    
   if(x == 15){
      next	 
   }	   
   cat("value of x : " , x ,"\n")    
}

When the above code is compiled and executed, it produces the following result −

value of x :  11 
value of x :  12 
value of x :  13 
value of x :  14 
value of x :  16 
value of x :  17 
value of x :  18 
value of x :  19 
value of x :  20 

Example - Using next statement in for loop

v <- LETTERS[1:10]
for ( i in v) {
   if(i == "C"){
      next
   }
   print(i)
}

When the above code is compiled and executed, it produces the following result −

[1] "A"
[1] "B"
[1] "D"
[1] "E"
[1] "F"
[1] "G"
[1] "H"
[1] "I"
[1] "J"
