combGOGraph {GOstats} | R Documentation

## Combine GO Graphs

### Description

Given two GO graphs this function combines them into a single graph and returns that.

### Usage

    combGOGraph(g1, g2)

### Arguments

`g1` | An instance of a `graph`.
`g2` | An instance of a `graph`.

### Details

A new `graph` object is created by linking the two supplied graphs together. Since they are both GO graphs they will share, at least, the GO root node.

This could probably be replaced by the `union` function in the `graph` package.

### Value

A graph containing the union of the nodes and edges in the two graphs.

### Author(s)

R. Gentleman

### Examples

     g1 <- oneGOGraph("GO:0003680", GOMFPARENTS)
     g2 <- oneGOGraph("GO:0003701", GOMFPARENTS)
     g3 <- combGOGraph(g1, g2)
