translateKEGGgraph {KEGGgraph} | R Documentation

## Tranlate the KEGG graph from being indexed by KEGGID to another identifer

### Description

The function translates the KEGG graph into a graph of equivalant topology while index with unique identifiers given by user. The new identifiers could be, for example, GeneSymbol or other identifiers mapped to KEGGID.

### Usage

    translateKEGGgraph(graph, newNodes)

### Arguments

`graph` | A KEGG graph
`newNodes` | A character vector giving the new nodes, must be of the same length and same order of the nodes of the given graph

### Details

The function is still experimental and users are welcomed to report any difficulties

### Value

Another graph indexed by the given identifier

### Examples

    sfile <- system.file("extdata/hsa04010.xml",package="KEGGgraph")
    gR <- parseKGML2Graph(sfile,expandGenes=TRUE)

    subG <- subKEGGgraph(c("hsa:1848","hsa:1432","hsa:2002","hsa:8986"),gR)
    symbols <- c("DUSP6","MAPK14","ELK1","RPS6KA4")
    sub2G <- translateKEGGgraph(subG, symbols)
    sub2G
    nodes(sub2G)

    if(require(Rgraphviz) & interactive()) {
    plot(sub2G, "neato")
    }
