Gene Ontology Biological Process (GOBP).


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 This data is prepared based on


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')
