Repeat loop does not have any condition to terminate the loop, a programmer must specifically place a condition within the loop’s body and use the declaration of a break statement to terminate this loop. It is a simple loop that will run the same statement or a group of statements repeatedly until the stop condition has been encountered. 120 is displayed beyond the scope of the loop. When i becomes 5, the loop is terminated and the factorial of 5 i.e. i should be less than or equal to 5, and after that factorial is multiplied with the value of i, then i is incremented. In each iteration of the loop, the condition is checked i.e. i will be used for iterating over the loop, and factorial will be used for calculating the factorial. Here, at first, the variable n is assigned to 5 whose factorial is going to be calculated, then variable i and factorial are assigned to 1. R – For loop Syntax: for (value in sequence) It is an entry controlled loop, in this loop the test condition is tested first, then the body of the loop is executed, the loop body would not be executed if the test condition is false. For loop is commonly used to iterate over items of a sequence. It is a type of control statement that enables one to easily construct a loop that has to run statements or a set of statements multiple times. There are three types of loop in R programming:
In order to execute the identical lines of code numerous times in a program, a programmer can simply use a loop. The control statement controls the execution of statements depending on the condition and the loop body consists of the set of statements to be executed. There are two components of a loop, the control statement, and the loop body. Any time the query is asked in the loop, it is known as an iteration of the loop. The same query is asked again and again until further action is taken. If the answer to that query requires an action, it will be executed. The word ‘looping’ means cycling or iterating.Ī loop asks a query, in the loop structure. A loop is a control statement that allows multiple executions of a statement or a set of statements. Loops come in the class of the most fundamental and strong programming concepts. In R programming, we require a control structure to run a block of code multiple times.

The following simple example repeats the same command 5 times. The for loop is probably the easiest way to repeat something over and over.
