GOBPCHILDREN {GO.db} | R Documentation

## Annotation of GO Identifiers to their Biological Process Children

### Description

This data set describes associations between GO molecular function (BP) terms and their direct children BP terms, based on the directed acyclic graph (DAG) defined by the Gene Ontology Consortium. The format is an R object mapping the GO BP terms to all direct children terms, where a direct child term is a more specific GO term that is immediately preceded by the given GO term in the DAG.

### Details

Each GO BP term is mapped to a vector of children GO BP terms.

Biological process is defined as the broad biological goals, such as mitosis or purine metabolism, that are accomplished by ordered assemblies of molecular functions as defined by Gene Ontology Consortium.

Mappings were based on data provided by: Gene Ontology ( ftp://ftp.geneontology.org/pub/go/godatabase/archive/latest ) on 200803

### Examples

      # Convert the object to a list
      xx <- as.list(GOBPCHILDREN)
      # Remove GO IDs that do not have any children
      xx <- xx[!is.na(xx)]
      if(length(xx) > 0){
         # Get the parent GO IDs for the first elents of xx
            goids <- xx[[1]]
            # Find out the GO terms for the first parent goid
            GOID(GOTERM[[goids[1]]])
            Term(GOTERM[[goids[1]]])
