To create an if-then statement in R, use the if() {} function. The if() function has two main elements, a logical test in the parentheses and conditional code in curly braces. The code in the curly braces is conditional because it is only evaluated if the logical test contained in the parentheses is TRUE.

How do you write an IF and ELSE statement in R?

To generalize, if-else in R needs three arguments:

  1. A statement (e.g. comparison operator) that evaluates to TRUE or FALSE.
  2. The value that R should return if the comparison operator is TRUE.
  3. The value that R should return if the comparison operator is FALSE.

%>% is called the forward pipe operator in R. It provides a mechanism for chaining commands with a new forward-pipe operator, %>%. This operator will forward a value, or the result of an expression, into the next function call/expression.

Here, test_expression can be a logical or numeric vector, but only the first element is taken into consideration. In the case of numeric vector, zero is taken as FALSE, rest as TRUE.

What are control structures in R?

Control structures set a condition and tell R what to do when that condition is met or not met. And unlike some kids, R will always do what we tell it to! You can learn more about control structures in the R documentation if you would like.
