An R object that contains information on Human Phenotype Mode of Inheritance 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://purl.obolibrary.org/obo/hp.obo.
ig.HPMI <- dRDataLoader(RData = "ig.HPMI")
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')
