Compute MDS coordinates for expression data using limma's plotMDS.
mdsinfo(matrix, top, gene.selection)
A list object from "plotMDS() " containing MDS coordinates and eigenvalues.
A DGEList object.
Integer. Number of top most variable genes to include in MDS.
Method for gene selection: one of "pairwise", "common", or "logFC".
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.
