In this R tutorial you’ll learn how to handle the error message “attempt to apply non-function”.

Table of contents:

Let’s do this:

 

Example 1: Replicate the Error – attempt to apply non-function

Example 1 explains how to reproduce the error “attempt to apply non-function” in R.

Let’s assume that we want to perform a mathematical operation based on the values 2 and 3. Then we might try to execute some code as shown below:

2 (3)                       # No function specified
# Error: attempt to apply non-function

The RStudio console returns the error “attempt to apply non-function”. This is because we didn’t specify a mathematical operator or a function between the two values.

Next, I’ll explain how to solve this problem…

 

Example 2: Fix the Error – attempt to apply non-function

This example shows how to avoid the error message “attempt to apply non-function”.

For this, we simply have to insert a mathematical operator between our two values. In this example, we’ll use the + sign:

2 + (3)                     # Plus sign between values
# [1] 5

No error – looks good!
