Plot Densities
Plots the non-parametric density estimates using values contained in the columns of a matrix.
plotDensity(mat, ylab = "density", xlab="x", type="l", col=1:6,
na.rm = TRUE, ...)
plotDensity.AffyBatch(x, col = 1:6, log = TRUE,
which=c("pm","mm","both"),
ylab = "density",
xlab = NULL, ...)mat |
a matrix containing the values to make densities in the columns. |
x |
an object of class |
log |
logical value. If |
which |
should a histogram of the PMs, MMs, or both be made? |
col |
the colors to use for the different arrays. |
ylab |
a title for the y axis. |
xlab |
a title for the x axis. |
type |
type for the plot. |
na.rm |
handling of |
... |
graphical parameters can be given as arguments to

The list returned can be convenient for plotting large input matrices with different colors/line types schemes (the computation of the densities can take some time).
To match other functions in base R, this function should probably be
called matdensity, as it is sharing similarities with
matplot and matlines.
It returns invisibly a list of two matrices ‘x’ and ‘y’.
