folders (version 0.1.0)

create_folders: Create Folders

Description

Create a standardized set of folders under a parent folder of an R project.

Usage

create_folders(folders, showWarnings = FALSE, recursive = TRUE)

Value

(vector) A named vector for the results of "dir.create" operations.

Arguments

folders

(list) A named list of standard folders for an R project.

showWarnings

(boolean) Show warnings. See: base::dir.create(). (Default: FALSE)

recursive

(boolean) Support recursive folder creation. See: base::dir.create(). (Default: TRUE)

Details

For each folder in the "folders" list, here::here() and base::dir.create() are used to create a subfolder under the parent folder. Warnings are silenced in case the folder already exists. Recursive folder creation is supported. These two features can be controlled with the "showWarnings" and "recursive" parameters. A TRUE value in the returned vector means the folder was created by dir.create(). If a folder already exists, the returned vector will have a FALSE value for that folder.

Examples

# Create list of standard folder names and store in a configuration file
conf_file <- tempfile("folders.yml")     # Using tempfile() for testing only
folders <- get_folders(conf_file)

# Testing only: Append folder names to parent folder path --
#               This would NOT be needed or desired in normal usage
folders <- lapply(folders, function(x) file.path(tempdir(), x))

# Create a folder for each item in "folders" list
result <- create_folders(folders)

# Check results
file.exists(conf_file)
sapply(folders, dir.exists)

# Create a data file and confirm that it exists
df <- data.frame(x = letters[1:3], y = 1:3)
file_path <- here::here(folders$data, "data.csv")
write.csv(df, file_path, row.names = FALSE)
file.exists(file_path)
