In bedapub/ribiosExpression: Expression Analysis with RibiosExpression

Plot a DesignContrast object with two heatmaps

Description

The function plots a ComplexHeatmap containing two matrices, one of the design matrix and the other of the contrast matrix.

Usage

## S3 method for class 'DesignContrast'
plot(
  x,
  y = NULL,
  title = NULL,
  clusterDesign = FALSE,
  clusterSamples = FALSE,
  clusterContrasts = FALSE,
  ...
)

Arguments

x	A DesignContrast object
y	NULL, ignored
title	Title of the object, used in the title of the heatmaps
clusterDesign	Logical, cluster rows of the design matrix
clusterSamples	Logical, cluster columns of the design matrix
clusterContrasts	Logical, cluster rows of the contrast matrix (notice that the contrast matrix required by limma is the transposed contrast matrix)
...	Other parameters passed to Heatmap

Value

Heatmap object

Examples

myFac <- gl(3,3, labels=c("baseline", "treat1", "treat2"))
myDesign <- model.matrix(~myFac)
colnames(myDesign) <- c("baseline", "treat1", "treat2")
myContrast <- limma::makeContrasts(contrasts=c("treat1", "treat2"), levels=myDesign)
res1 <- DesignContrast(myDesign, myContrast, groups=myFac)
res2 <- DesignContrast(myDesign, myContrast, groups=myFac, dispLevels=c("C", "T1", "T2"))
plot(res1, title="DesCon 1")
plot(res2, title="DesCon 1 (identical)")
