Description

Plots the non-parametric density estimates using values contained in the columns of a matrix.

Usage


plotDensity(mat, ylab = "density", xlab="x", type="l", col=1:6,...)

plotDensity.AffyBatch(x, col = 1:6, log=TRUE,
which=c("pm","mm","both"), ylab = "density", xlab = NULL, ...)

Arguments

mat A matrix containing the values to make densities in the columns.
x A object of clase AffyBatch
log logical value. If TRUE the log of the intensities in the AffyBatch are plotted.
which should a histogram of the PMs, MMs, or both be made?
col The colors to use fot the different arrays
ylab a title for the y axis.
xlab a title for the x axis.
type type for the plot.
... graphical parameters can be given as arguments to plot
