What does next function do in loops in R
This recipe explains what does next function do in loops in R
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 :" 1 2 "skip this and next" 4 5 6 7 8 9 10
