Visualization of sequential decomposition

Description

Plot to show the sum of squares decomposition for each gene into parts according to all variables.

Usage

Plot.sequential(xx, formula, model.dat = NULL, test.genes = NULL, name.geneset = "")

Arguments

xx Matrix of gene expression data, where columns correspond to samples and rows to genes. The data should be properly normalized beforehand (and log- or otherwise transformed). Missing values are not allowed. Gene and sample names can be included as the row and column names of xx.
formula Model formula for the linear model.
model.dat Data frame that contains all the variable information for each sample.
test.genes Vector of gene names or gene indices specifying a gene set.
name.geneset Name of the plotted geneset.
