data_mesh_thesaurus {puremoe}

Download and Combine 'MeSH' and Supplemental Thesauruses

Description

This function downloads and combines the 'MeSH' (Medical Subject Headings) Thesaurus and a supplemental concept thesaurus. 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.

Usage

data_mesh_thesaurus(
  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.

Value

A data.table containing the combined MeSH and supplemental thesaurus data.

Examples
