Bicluster Visualization

Share:

Description

Creates a heatmap contrasting the data values for a bicluster's features across the bicluster with those features' values across the remainder of the dataset.

Usage

1
plotBicluster(x,dataset,col=gray(seq(from=1,to=0,length=100)))

Arguments

x

Bicluster object returned from GABi

dataset

Numeric matrix in which bicluster x was discovered

col

Colors to use in heatmap

Details

Uses heatmap to generate a false color image that illustrates the data values corresponding to the bicluster x. Default color is grayscale. A black/white bar along the top of the heatmap indicates the extent of bicluster membership (i.e. columns of the heatmap below the black bar come from data columns that were in the bicluster).

Value

An object returned by heatmap. That is, invisibly, a list with components:

rowInd

row index permutation vector as returned by order.dendrogram

colInd

column index permutation vector
