Recipe Objective

How to write a if else condition in R ? Conditional statements control the flow of the program. In if-else condition, the if () statement is executed when the condition is TRUE. If the expression returns a FALSE value, then the else() statement is executed. This recipe demonstrates an example of an if-else statement..

Step 1- Create a vector

x <- c(list(123,2.5,"hello"))

Step 2 - if else statement

if ("hi" %in% x){ print("hi present in x") } else { print("hi not present in x") }
"Output of the code is hi not present in x"  

Step 3- Nested if-else statement

Nested if-else statement executes only that statement which returns TRUE value.

if (13 %in% x){ print("13 is present in x") } else if (123 %in% x){ print("123 is present in x") } else{ print("not present in x") }
 "Output of the code is 123 is present in x"
