plotBipartite: Internal function to plot a bipartite graph

In FELLA: Interpretation and enrichment for metabolomics data

Description

This function plots a bipartite graph, tailored for the hypergeometric over representation analysis. As the nodes can only be compounds and pathways, the layout is simple and bipartite.

Usage

plotBipartite(graph = NULL, layout = FALSE, ...)

Arguments

graph	Graph result that must come from the hypergeometric test analysis
layout	Logical, should the plot be returned as a layout?
...	Additional parameters passed to plot.igraph

Value

If layout = F then the value returned is invisible(). Otherwise, the layout is returned, also in an invisible fashion.

Examples

## This function is internal
data(FELLA.sample)
data(input.sample)
## Enrich input
obj <- enrich(
compounds = input.sample, 
data = FELLA.sample, 
method = "hypergeom")
## Generate the bipartite graph (only in the hypergeometric test)
g <- generateResultsGraph(
method = "hypergeom", 
threshold = 1, 
object = obj, 
data = FELLA.sample)
## Plot it
FELLA:::plotBipartite(g)
