plotHeatmap: A function to generate heatmap panels sorted by integrated cluster assignment.

Description

A function to generate heatmap panels sorted by integrated cluster assignment.

Usage

plotHeatmap(fit,datasets,type=c("gaussian","binomial","poisson","multinomial"), sample.order=NULL,row.order=NULL,sparse=NULL,threshold=rep(0.25,length(datasets)), width=5,scale=rep("none",length(datasets)),col.scheme=rep(list(bluered(256)), length(datasets)), chr=NULL, plot.chr=NULL, cap=NULL)

Arguments

fit
A iCluster object.
datasets
A list object of data matrices.
type
Types of data in the datasets.
sample.order
User supplied cluster assignment.
row.order
A vector of logical values each specificy whether the genomic features in the corresponding data matrix should be reordered by similarity. Default is TRUE.
sparse
A vector of logical values each specificy whether to plot the top cluster-discriminant features. Default is FALSE.
threshold
When sparse is TRUE, a vector of threshold values to include the genomic features for which the absolute value of the associated coefficient estimates fall in the top quantile. threshold=c(0.25,0.25) takes the top quartile most discriminant features in data type 1 and data type 2 for plot.
width
Width of the figure in inches
scale
A vector of logical values each specify whether data should be scaled. Default is FALSE.
col.scheme
Color scheme. Can use bluered(n) in gplots R package.
chr
A vector of chromosome number.
plot.chr
A vector of logical values each specificy whether to annotate chromosome number on the left of the panel. Typically used for copy number data type. Default is FALSE.
cap
Image color option

Value

no value returned.
