Get Variable Names which are not Part of the Given Vector

Description

If you have stored variable names inside a character vector, this function gives you the inverse variable name vector.

Usage

inverse(data_frame, var_names)

Arguments

data_frame	The data frame from which to take the variable names.
var_names	A character vector of variable names.

Value

Returns the inverse vector of variable names compared to the given vector.

Examples

# Example data frame
my_data <- dummy_data(1000)

# Get variable names
var_names <- c("year", "age", "sex")
other_names <- my_data |> inverse(var_names)

# Can also be used to just get all variable names
all_names <- my_data |> inverse(NULL)
all_names <- my_data |> inverse(character(0))
