R Nested If

Sure! Nested "if" statements in R allow you to have multiple levels of conditions within your code. Each "if" statement can have its own "else" block, and you can place another "if" statement inside either the "if" or "else" block of another "if" statement.

Here's a simple explanation with an example:

Let's say you want to categorize a person's age into different groups: "child", "teenager", "adult", and "senior". You can use nested "if" statements to achieve this.

Explanation:

• The outermost "if" statement checks if the age is less than 13. If it is, it prints "You are a child".
• If the age is not less than 13, the code inside the else block is executed.
• Inside the else block, there's another "if" statement. This checks if the age is less than 20. If it is, it prints "You are a teenager".
• If the age is not less than 20, the code inside the else block of this inner "if" statement is executed.
• Inside this else block, there's another "if" statement. This checks if the age is less than 65. If it is, it prints "You are an adult".
• If the age is not less than 65, the code inside the else block of this inner "if" statement is executed, which prints "You are a senior".

So, based on the value of the age variable, the appropriate message will be printed.
