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.

Flowchart
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
}
