## Plot Densities

### 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`
