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://www.geneontology.org/ontology/obo_format_1_2/gene_ontology.1_2.obo.
ig.GOBP <- dRDataLoader(RData = "ig.GOBP")
an object of class "igraph". As a direct graph, it has attributes to vertices/nodes and edges:
vertex attributes: "name" (i.e. "Term ID"), "term_id" (i.e. "Term ID"), "term_name" (i.e "Term Name") and "term_distance" (i.e. Term Distance: the distance to the root; always 0 for the root itself)
edge attributes: "relation" (either 'is_a' or 'part_of')
