Plots the density of the probe signals on the array.
# S3 method for AffymetrixCelFile
plotDensity(this, subset=NULL, types=NULL, ..., xlim=c(0, 16), xlab=NULL,
ylab="density (integrates to one)", log=TRUE, annotate=TRUE, verbose=FALSE)
Returns nothing.
The subset of probes to considered before any
filtering by probe type is applied.
If a vector
of double
s, the cell indices.
If a scalar double
in [0,1], the fraction of cells, which can
be used to speed up the plotting if approximate densities are
acceptable.
if NULL
, all cells are considered.
The type of probes to include, e.g. "all"
,
"pmmm"
, "pm"
, and "mm"
.
Additional arguments passed to
plotDensity.numeric
.
The range on the x axis.
The labels on the x and the y axes.
If TRUE
, the density of the log (base 2) values are
used, otherwise the non-logged values.
A logical
or a Verbose
object.
