\begin{Description}\relax
This data set describes associations between GO molecular function (BP)
terms and their ancestor BP terms, based on the directed acyclic
graph (DAG) defined by the Gene Ontology Consortium. The format is an R
environment mapping the GO BP terms to all ancestor terms, where an
ancestor 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.).
\end{Description}
\begin{Details}\relax
Each GO BP term is mapped to a vector of offspring 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:

\begin{ExampleCode}
  require("GO", character.only = TRUE) || stop("GO unavailable")
  # Convert the environment object to a list
  xx <- as.list(GOBPOFFSPRING)
  # Remove GO IDs that do not have any offspring
  xx <- xx[!is.na(xx)]
  if(length(xx) > 0){
    # Get the offspring GO IDs for the first two elents of xx
    goids <- xx[1:2]
  }
