Get file path to penguins.csv and penguins_raw.csv files

Description

palmerpenguins comes bundled with two csv files in its inst/extdata directory. This function make them easy to access.

Usage

path_to_file(path = NULL)

Arguments

path

Name of file in quotes with extension; "penguins.csv" and "penguins_raw.csv" will work. If NULL, the example files will be listed.

Details

The data in each file is the same as penguins and penguins_raw, but without the variable types.

Source

This function is adapted from readxl::readxl_example().

Examples

path_to_file()
path_to_file("penguins_raw.csv")
head(read.csv(path_to_file("penguins.csv")))
