How to do it…

To check whether the value of the a variable is an even or odd number, the R code is as follows:

        a <- 9        if(a %% 2==0){          print("This is an even number")        } else {          print("This is an odd number")        }

To check whether a given number is an odd or even, first, you must calculate the remainder after dividing the number by 2. Then, if the remainder is a 0, the number is an even number, otherwise it is an odd number.
