getMatrix: Get matrix for the desired methodology

In FELLA: Interpretation and enrichment for metabolomics data

Description

Extractor function for the matrices of hypergeometric, diffusion and PageRank methodologies

Usage

getMatrix(data, method)

Arguments

data	FELLA.DATA object
method	Character, exactly one of: "hypergeom", "diffusion", "pagerank"

Value

Matrix for the desired methodology (internal usage)

Examples

## This function is internal
attach(environment(FELLA:::getMatrix))
data(FELLA.sample)
# When a matrix is loaded:
x <- getMatrix(FELLA.sample, "hypergeom")
dim(x)
# When it is not:
y <- getMatrix(FELLA.sample, "diffusion")
dim(y)
y
