\title{
Barplot
}
\description{
A barplot of FPKM values with confidence intervals for a given gene, set of genes, or features of a gene (e.g. isoforms, TSS, CDS, etc).
}
\usage{
\S4method{expressionBarplot}{CuffFeatureSet}(object, logMode=TRUE, pseudocount=1.0, showErrorbars=TRUE, showStatus=TRUE, ...)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{object}{
An object of class ('CuffFeatureSet','CuffGeneSet','CuffFeature','CuffGene')
}
  \item{logMode}{
A logical value whether or not to draw y-axis on log10 scale. Default = FALSE.
}
  \item{pseudocount}{
Numerical value added to each FPKM during log-transformation to avoid errors.
}
  \item{showErrorbars}{
A logical value whether or not to draw error bars. Default = TRUE
}
  \item{showStatus}{
A logical value whether or not to draw visual queues for quantification status of a given gene:condition. Default = TRUE
}
  \item{\dots}{
Additional arguments.

Need to implement logMode and features for this plotting method.
