GOCCANCESTOR {GO} | R Documentation |
This is an R environment (hash table) mapping GO ids to all the GO ids of their ancestors under cellular component (CC). Ancestors are defined as the direct or indirect parent/grand parent nodes of a given node for a GO id based on the directed acyclic graph defined by Gene Ontology Consortium. GO terms for ancestor nodes are more general
GO ids are keys and the corresponding ancestor GO ids are values. Values are vectors of GO ids for all the ancestor of the key GO id. GO ids that do not have any offspring node are assigned NA as the values.
Cellular component is defined as the subcellular structures, locations, and macromolecular complexes; examples include nucleus, telomere, and origin recognition complex as defined b y Gene Ontology Consortium.
Mappings were based on data provided:
