What does next function do in loops?

This recipe explains what does next function do in loops

Recipe Objective

What does the next function do in loops ? Loops are used to execute a particular block of code for a specified number of time for a given condition. If the user wants to skip the current iteration in a loop and jump to the next iteration without terminating out of the loop, the next () function can be used. next function can be used inside a for loop as well as in a while loop. This recipe demonstrates an example of the next function using a for loop.

Step 1 - Create a vector

a <- c(1:10)

Step 2 - Using next()

Once the for loop begins , and the next function is found, the next() skips that iteration and jumps to the next iteration.

for (i in a) { if (i==3) { print("skip this and next",i) next } print(i) }
"Output of the code is :"
