mdsinfo: mdsinfo

Description

Compute MDS coordinates for expression data using limma's plotMDS.

Usage

mdsinfo(matrix, top, gene.selection)

Value

A list object from "plotMDS() " containing MDS coordinates and eigenvalues.

Arguments

matrix

A DGEList object.

top

Integer. Number of top most variable genes to include in MDS.

gene.selection

Method for gene selection: one of "pairwise", "common", or "logFC".

Details

This function performs multidimensional scaling (MDS) on a DGEList or log-expression matrix using limma's "plotMDS() " function. It returns the MDS object containing coordinates and eigenvalues without generating a plot.
