An R object that contains information on Gene Ontology Biological
Process terms. These terms are organised as a direct acyclic graph
(DAG), which is further stored as an object of the class 'igraph' (see
http://igraph.org/r/doc/aaa-igraph-package.html). This data is
prepared based on
http://sourceforge.net/p/diseaseontology/code/HEAD/tree/trunk/HumanDO.obo.
Usage
data(obo.DO)
Arguments
Value
an object of class "igraph". As a direct graph, it has attributes to
vertices/nodes:
vertex attributes: "name" (i.e. Term ID), "term_id" (i.e.
Term ID), "term_name" (i.e. Term Name), "term_namespace" (i.e. Term
Namespace), and "term_distance" (i.e. Term Distance: the distance to
the root; always 0 for the root itself)
