addlegend: adds a legend to a Sushi plot

In dphansti/Sushi: Tools for visualizing genomics data

Description

This function adds a legend to Sushi plots that have a colorby function (e.g. plotHic, plotGenes, and plotBedpe)

Usage

addlegend(range, title = "", labels.digits = 1, palette = topo.colors,
  side = "right", labelside = "left", xoffset = 0.1, width = 0.05,
  bottominset = 0.025, topinset = 0.025, tick.num = 5,
  tick.length = 0.01, txt.font = 1, txt.cex = 0.75, title.offset = 0.05,
  title.font = 2, title.cex = 1)

Arguments

range	the rang of values to be plotted. ie c(min,max)
title	title of values to be mapped
labels.digits	Number of digits after the decimal point to include in labels
palette	color palette to use
side	side of plot to place legend ('right','left')
labelside	side of legend to place legend title
xoffset	fraction of plot to offset the legend
width	width as a fraction of the plot width
bottominset	inset from the bottom of the blot as a fraction of the plot width
topinset	inset from the top of the blot as a fraction of the plot width
tick.num	desired number of tickmarks
tick.length	length of tick marks
txt.font	font type of legend text
txt.cex	font size of legned text
title.offset	offset of title from the key
title.font	font type of legend title
title.cex	font size of legned text

Examples

data(Sushi_HiC.matrix)

chrom            = "chr11"
chromstart       = 500000
chromend         = 5050000

phic = plotHic(Sushi_HiC.matrix,chrom,chromstart,chromend,max_y = 20,zrange=c(0,28),palette = topo.colors,flip=FALSE)

labelgenome(chrom,chromstart,chromend,side=1,scipen=20,n=4,scale="Mb",edgeblankfraction=0.20,line=.18,chromline=.5,scaleline=0.5)

addlegend(phic[[1]],palette=phic[[2]],title="score",side="right",bottominset=0.4,topinset=0,xoffset=-.035,labelside="left",width=0.025,title.offset=0.035)
