basepenguins (version 0.1.0)

example_files: List or find example files from basepenguins package

Description

These functions provides access to example files included with the basepenguins package. When example_files() is called with path = NULL, it lists available example files. When called with a specific path, it returns the full path to that file. example_dir() provides the path to the directory containing the examples, and also takes a copy.dir argument which, if specified, will copy all the example files to a new directory. This is useful for testing the convert_dir_inplace() and convert_files_inplace() functions without overwriting package files.

Usage

example_files(path = NULL, full.names = FALSE, recursive = TRUE)
example_dir(copy.dir = NULL)

Value

example_files:

• If path = NULL, a character vector of available file/directory names.

• If path is specified, the absolute path to the requested file.

example_dir:

• If copy.dir = NULL, the absolute path to the directory containing all examples.

• If copy.dir is specified, the specified directory is created if it doesn't already exist, and all example files are copied into it, preserving nesting structure. The absolute path to the directory is returned invisibly.

Arguments

path

Character string. If NULL (default), lists all available example files. If specified, returns the full path to the specified file or directory.

full.names

Logical. If TRUE, returns full file paths rather than relative paths. Only used when path = NULL. Default is FALSE.

recursive

Logical. If TRUE, lists files in subdirectories recursively. Only used when path = NULL. Default is TRUE.

copy.dir

Character string. A directory name or path to a directory into which the files in the example directory will be copied. If NULL (default) the files will not be copied.

Details

There are four example files in the example directory:

• penguins.R - an R script using the palmerpenguins package

• no_penguins.Rmd - an Rmarkdown file with ends_with("_mm"), but not in the context of the palmerpenguins package

• nested/penguins.qmd - a Quarto document that uses the palmerpenguins package

• nested/not_a_script.md - contains library(palmerpenguins), but is not a script, i.e. not one of the default extensions for the convert functions.

Examples

# List all files in the example directory provided by the package
example_files()

# Get the full path to a specific example files
example_files("penguins.R") # path/to/basepenguins/extdata/penguins.R
example_files("nested/penguins.qmd")

# Get the path to the directory containing the example files
example_dir() # path/to/basepenguins/extdata/
.old_wd <- setwd(tempdir())
# Copy all files in the example directory
example_dir(".") # copy example files into working directory
example_dir("examples") # create subdirectory
setwd(.old_wd)
