I was confused when reading the description of the object GOCCPARENTS in GO.db package. I think all MF should be replaced by CC for that object. I quote the description and the details from the manual reference:

Description

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.).

Details

Each GO CC term is mapped to a vector of offspring GO MF terms. Cellular component is defined as the subcellular structures, locations, and macromolecular com- plexes; examples include nucleus, telomere, and origin recognition complex as defined b y Gene Ontology Consortium.

Mappings were based on data provided: Gene Ontology http://current.geneontology.org/ontology/go- basic.obo With a date stamp from the source of: 2022-07-01

Thank you very much.
