Nested ifelse Statement in R (2 Examples)

In this article you’ll learn how to apply nested ifelse statements in the R programming language.

Here’s how to do it.

Example 1: Nested ifelse Statement with Multiple TRUE Conditions

This section illustrates how to nest two ifelse statements in R. Have a look at the following R code:

ifelse(test = 5 > 3,                  # First test condition
 
       yes = ifelse(test = 5 > 4,     # Second test condition
                    yes = "TRUE Twice",
                    no = "Yes & No"),
 
       no = "No")
# "TRUE Twice"

The previous R syntax nests two ifelse statements. The second ifelse statement is applied in case the first logical test condition is TRUE.

In this example, the first and the second test conditions are TRUE. For that reason, the nested ifelse statement returns the output “TRUE Twice”.

Example 2: Nested ifelse Statement with TRUE & FALSE Conditions

Example 2 shows how to create a nested ifelse statement where the first condition is TRUE and the second condition is FALSE:

ifelse(test = 5 > 3,                  # First test condition
 
       yes = ifelse(test = 5 <= 4,    # Second test condition
                    yes = "TRUE Twice",
                    no = "Yes & No"),
 
       no = "No")
# "Yes & No"

The output is “Yes & No”.
