An edgelist network representing the hierarchical structure of the Medical Subject Headings (MeSH) terms.
Format
A data.table with the following columns:
- from_id
A character vector representing the MeSH identifier of the parent term.
- to_id
A character vector representing the MeSH identifier of the child term.
Source
The MeSH hierarchy data was obtained from the National Library of Medicine's Medical Subject Headings (MeSH) database (https://www.nlm.nih.gov/mesh/).
Details
The `mesh_hierarchy` data frame is an edgelist network, where each row represents a directed edge from a parent MeSH term (`from_id`) to a child MeSH term (`to_id`). This structure captures the hierarchical relationships between MeSH terms.
Examples
library(labyrinth)
data(mesh_hierarchy, package = "labyrinth")
