In this guide we will discuss about 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.

Example 1: next in repeat loop
a <- 1 repeat { if(a == 10) break if(a == 5){ next } print(a) a <- a+1 }
Output :

Example 2: next in while loop
a<-1 while (a < 10) { if(a==5) next print(a) a = a + 1 }
Output :

Example 3: next in for loop
x <- 1:10 for (val in x) { if (val == 3){ next } print(val) }
Output:

Example 4
a1<- c(10L,-11L,12L,-13L,14L,-15L,16L,-17L,18L) sum<-0 for(i in a1){ if(i<0){ next } sum=sum+i } cat("The sum of all positive numbers in array is=",sum)
Output:

Example 5
j<-0 while(j<10){ if (j==7){ j=j+1 next } cat("\nnumber is =",j) j=j+1 }
Output:
