The code returns numbers from 1 to 5.

for Loop

This is a repetition control structure that helps R programmers to write a loop that executes a particular section of code for a specific number of times. The statement takes the basic syntax given below:

for ( value in vector ) {

statements

}

The for loop is very flexible since it is not limited to numbers or integers as the input. We can pass logical vectors, character vectors, and expressions or lists to it. Consider the example given below:

l <- LETTERS[ 1 : 5 ]

for ( j in l) {

print ( j)

}
