BCheatmap {s4vd}

Overlap Heatmap for the visualization of overlapping biclusters

Description

Heatmap function to plot biclustering results. Overlapping biclusters are indicated by colored rectangles.

Usage

BCheatmap(X, res, cexR = 1.5, cexC = 1.25, axisR = FALSE, axisC= TRUE,
heatcols = maPalette(low="blue",mid="white",high="red", k=50),
clustercols = c(1:5), allrows = FALSE, allcolumns = TRUE)

Arguments

X

the data matrix

res

the biclustering result

cexR

relativ font size of the row labels

cexC

relativ font size of the column labels

axisR

if TRUE the row labels will be plotted

axisC

if TRUE the column labels will be plotted

heatcols

a character vector specifing the heatcolors

clustercols

a character vector specifing the colors of the rectangles that indicate the rows and columns that belong to a bicluster

allrows

if FALSE only the rows assigned to any bicluster will be plotted

allcolumns

if FALSE only the columns assigned to any bicluster will be plotted
