oneGOGraph {GOstats} | R Documentation

## Build a GO graph for one identifier

### Description

Given a single GO identifier and a set of mappings to the less specific sets of nodes this function will construct the graph that includes that node and all children down to the root node for the ontology.

### Usage

    oneGOGraph(x, dataenv)

### Arguments

`x` | A length one character vector with the name of the term.
`dataenv` | An environment for finding the parents of that term.

### Details

For any gene we define the induced GO graph to be that graph, based on the DAG structure (child - parent) of the GO ontology of terms.

### Value

The induced GO graph (or NULL) for the given GO identifier.

     g3 <- combGOGraph(g1, g2)

    if( require(Rgraphviz) && interactive() )
      plot(g3)
