## S4 method for signature 'ExpressionSet'
density(x, logMode=TRUE, xlab = NULL, ylab = "density", type = "l", 
	col=1:dim(x)[2], lty=1:dim(x)[2], lwd=1, xlim = NULL, index.highlight = NULL, color.highlight = 2, 
	symmetry = NULL, addLegend = TRUE, legendPos="topright", subset = NULL, main="", ...)

Arguments

x

a ExpressionSet object

logMode

determine whether the density plot is based on a log2 scale

xlab

xlab of the density plot

ylab

ylab of the density plot

type

parameter of plot function

col

line colors of the density plot

lty

line types of the density plot

lwd

line width of plot function

xlim

parameter of the plot function

index.highlight

the column index of the highlighted density curve

color.highlight

color of highlighted density curve

symmetry

the boundary position suppose to be symmetric distributed

addLegend

whether add legend to the plot or not

legendPos

the legend position. It can be a string specifying the position, or a length two vector specifying the x and y position. Please check legend for more details.

subset

subset of rows used to plot. It can be an index vector, or the length of a random subset

main

title for the plot

...

additional parameters for density function
