expressionPlot: Expression Plot

Description

A line plot (optionally with confidence intervals) detailing FPKM expression levels across conditions for a given gene(s) or feature(s)

Usage

"expressionPlot"(object, logMode=FALSE, pseudocount=1.0, drawSummary=FALSE, sumFun=mean_cl_boot, showErrorbars=TRUE, showStatus=TRUE, replicates=FALSE, facet = TRUE,...)

Arguments

object

An object of class ('CuffFeature' or 'CuffGene')

logMode

A logical value to draw y-axis (FPKM) on log-10 scale. Default = FALSE.

pseudocount

A numeric value added to FPKM to avoid errors on log-10 transformation.

drawSummary

A logical valuie. Draws a 'summary' line with mean FPKM values for each condition.

sumFun

Function used to determine values for summary line. Default = mean_cl_boot

showErrorbars

A logical value whether or not to draw error bars.

showStatus

A logical value whether or not to draw visual queues for quantification status of a given gene:condition. Default = TRUE

replicates

A logical value whether or not to plot individual replicates or aggregate condition values.

facet

A logical value whether or not to facet the plot by feature id (default=TRUE).
