MS_replaceNode {MetaboSignal} | R Documentation

## Replace nodes of the network

### Description

This function allows replacing node IDs of a network-table. It can be used to cluster the IDs of chemical isomers (e.g. alpha-D-glucose ("cpd:C00267"), D-glucose ("cpd:C00031"), and beta-D-glucose ("cpd:C00021")) into a single ID.

### Usage

    MS_replaceNode(node1, node2, network_table)

### Arguments

`node1` | character vector containing the node IDs to be replaced.
`node2` | character vector containing the ID that will be used as a replacement.
`network_table` | three-column matrix where each row represents and edge between two nodes. See function "MS_keggNetwork( )".

### Value

A three-column matrix corresponding to the input network-table with replaced nodes.

### Examples

    data(MetaboSignal_table)

    # Cluster D-glucose isomers ("cpd:C00267","cpd:C00221","cpd:C00031")

    glucoseClustered <- MS_replaceNode(node1 = c("cpd:C00267", "cpd:C00221"),
                                       node2 = "cpd:C00031", MetaboSignal_table)
