Description

Find related entries by using database cross-references.

Usage

keggLink(target, source)

Arguments

target

Either the name of a single KEGG database (list available via listDatabases(), a "T number" genome identifier, or a KEGG organism code (lists of both available via keggList("organism")).

source

The same as target, but may also be one or more KEGG identifiers.

Details

Many of the old KEGGSOAP functions whose names started with 'get', such as get.pathways.by.genes and get.pathways.by.reactions, are replaced by using keggLink (see examples).

Value

A named character vector.
