no applicable method for 'select' applied to an object of class "function"

This error message typically occurs when trying to apply the `select` function to a function object instead of a data frame.

For example, if you have defined a function called `my_function` and you accidentally try to apply `select` to it like this:

my_function %>% select(column1, column2)

You will get the error message: "no applicable method for 'select' applied to an object of class "function""

To fix this error, make sure you are applying the `select` function to a data frame, like this:

my_data_frame %>% select(column1, column2)
