Search for KG nodes using the Monarch Initiative search API

This function is a wrapper around the Monarch-hosted search API. It returns nodes (no edges) from the Monarch KG, fetched via an instance of monarch_engine().

monarch_search(query, category = NULL, limit = 10, ...)

Arguments

query: Search query string, e.g. "Cystic fibrosis"
category: A set of node category labels to limit the search to, e.g. c("biolink:Disease", "biolink:Gene")
limit: Maximum number of nodes to return. Default 10.
...: Parameters passed to monarch_engine().

Value

A local tbl_kgx graph with no edges.
