onto.MP: Mammalian Phenotype (MP).

In dcGOR: Analysis of Ontologies and Protein Domain Annotations

Description

An R object that contains information on Mammalian Phenotype 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 ftp://ftp.informatics.jax.org/pub/reports/MPheno_OBO.ontology.

Usage

data(onto.MP)

Value

an object of S4 class Onto. It has slots for "nodeInfo" and "adjMatrix"

• nodeInfo: an object of S4 class InfoDataFrame, describing information on nodes/terms including: "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)

• adjMatrix: an object of S4 class AdjData, containing adjacency data matrix, with rows for parent (arrow-outbound) and columns for children (arrow-inbound)
