Annotation of DO Identifiers to their Ancestors

Description

This data set describes associations between DO terms and their ancestor terms, based on the directed acyclic graph (DAG) defined by the Disease Ontology Consortium. The format is an R object mapping the DO terms to all ancestor terms, where an ancestor term is a more general DO term that precedes the given DO term in the DAG (in other words, the parents, and all their parents, etc.).

Details

Each DO term is mapped to a vector of ancestor DO terms.

Mappings were based on data provided by: Disease Ontology With a date stamp from the source of: 20150323 (sub_version 2806)

Examples

  # Convert the object to a list
  xx <- as.list(DOANCESTOR)
  # Remove DO IDs that do not have any ancestor
  xx <- xx[!is.na(xx)]
  if(length(xx) > 0){
    # Get the ancestor DO IDs for the first two elents of xx
    doids <- xx[1:2]
  }
