ig.HPPA: Human Phenotype Phenotypic Abnormality (HPPA).

In dnet: Integrative Analysis of Omics Data in Terms of Network, Evolution and Ontology

Description

An R object that contains information on Human Phenotype Phenotypic Abnormality 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.

Usage

data(ig.HPPA)

Value

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')
