GOMFOFFSPRING: Annotation of GO Identifiers to their Molecular Function...
In Bioconductor/GO.db: A set of annotation maps describing the entire Gene Ontology

Description Details References See Also Examples

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

Each GO MF term is mapped to a vector of offspring GO MF terms.

Molecular function is defined as the tasks performed by individual gene products; examples are transcription factor and DNA helicase as defined by Gene Ontology Consortium.

Mappings were based on data provided by: Gene Ontology ftp://ftp.geneontology.org/pub/go/godatabase/archive/latest-lite/ With a date stamp from the source of: 2018-Oct10

AnnotationDb-class for use of the select() interface.

## select() interface:
## Objects in this package can be accessed using the select() interface
## from the AnnotationDbi package. See ?select for details.

## Bimap interface:
# Convert the object to a list
xx <- as.list(GOMFOFFSPRING)
# Remove GO identifiers that do not have any offspring
xx <- xx[!is.na(xx)]
if(length(xx) > 0){
  # Get the offspring GO identifiers for the first two elents of xx
goids <- xx[1:2]
