multiHeatmap: Superfigure plots

In Repitools: Epigenomic tools

Description

This function takes a list of matrices and plots heatmaps for each one. There are several features for the spacing (X and Y), colour scales, titles and label sizes. If a matrix has row and/or column names, these are added to the plot.

Usage

multiHeatmap(dataList, colourList, titles = NULL, main = "", showColour = TRUE, xspace = 1, cwidth = 0.5, ystarts = c(0.05, 0.9, 0.925, 0.95, 0.98), rlabelcex = 1, clabelcex = 1, titlecex = 1.2, maincex = 1.5, scalecex = 0.7, offset=.001)

Arguments

dataList	A list of matrices to be plotted as different panels
colourList	A list of colourscales (if length 1, it is copied for all panels of the plot)
titles	A vector of panel titles
main	A main title
showColour	logical or logical vector, whether to plot the colour scale
xspace	The space between the panels (relative to number of columns). This can be either a scalar or a vector of length(dataList)+1
cwidth	widths of the colour scales relative to the width of the panels
ystarts	A vector of length 5 of numbers between 0 and 1 giving the relative Y positions of where the heatmaps, colourscale labels, colour scales, panel titles and main title (respectively) start
rlabelcex	character expansion factor for row labels
clabelcex	character expansion factor for column labels
titlecex	character expansion factor for panel titles
maincex	character expansion factor for main title
scalecex	character expansion factor for colour scale labels
offset	small offset to adjust scales for point beyond the colour scale boundaries

Value

This function is called for its output, a plot in the current device.

Examples

library(gplots)

cL <- NULL
br <- seq(-3,3,length=101)
col <- colorpanel(low="blue",mid="grey",high="red",n=101)
cL[[1]] <- list(breaks=br,colors=col)
br <- seq(-2,2,length=101)
col <- colorpanel(low="green",mid="black",high="red",n=101)
cL[[2]] <- list(breaks=br,colors=col)
br <- seq(0,20,length=101)
col <- colorpanel(low="black",mid="grey",high="white",n=101)
cL[[3]] <- list(breaks=br,colors=col)

testD <- list(matrix(runif(400),nrow=20),matrix(rnorm(100),nrow=20),matrix(rpois(100,lambda=10),nrow=20))
colnames(testD[[1]]) <- letters[1:20]
rownames(testD[[1]]) <- paste("row",1:20,sep="")

multiHeatmap(testD,cL,xspace=1)
