Download and Load 'MeSH' Trees Data

Description

This function downloads and loads the 'MeSH' (Medical Subject Headings) Trees data.

Usage

data_mesh_trees(
  path = NULL,
  use_persistent_storage = FALSE,
  force_install = FALSE
)

Arguments

path

A character string specifying the directory path where data should be stored. If not provided and persistent storage is requested, it defaults to a system-appropriate persistent location managed by 'rappdirs'.

use_persistent_storage

A logical value indicating whether to use persistent storage. If TRUE and no path is provided, data will be stored in a system-appropriate location. Defaults to FALSE, using a temporary directory.

force_install

A logical value indicating whether to force re-downloading of the data even if it already exists locally.

Details

The data is sourced from specified URLs and stored locally for subsequent use. By default, the data is stored in a temporary directory. Users can opt into persistent storage by setting 'use_persistent_storage' to TRUE and optionally specifying a path.

Value

A data frame containing the MeSH Trees data.

Examples

data <- data_mesh_trees()
