\title{
Density plot of CuffData
}
\description{
Creates a smoothed density plot, by sample, for log10 FPKM values from a cuffdiff run.
}
\usage{
\S4method{csDensity}{CuffData}(object, logMode=TRUE, pseudocount=1.0, labels, features=FALSE, ...)
\S4method{csDensity}{CuffFeatureSet}(object, logMode=TRUE, pseudocount=1.0, labels, features=FALSE, ...)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{object}{
An object of class CuffData.
}
  \item{logMode}{
A logical value of whether or not to log10-transform FPKM values.  By default this is TRUE.
}
  \item{pseudocount}{
Pseudocount value added to FPKM to avoid errors in log-transformation of true zero values.
}
  \item{labels}{
A list of tracking_id values or gene_short_name values used for 'callout' points on the density plot for reference. (Not implemented yet).
}
  \item{features}{
Will include all fields from 'features' slot in returned ggplot object.
Useful for further manipulations of plot object using feature-level attributes (e.g. gene_type, class_code, etc)
}
