QCplots: Quality Control visualizations

Description

A collection of ggplot2 visualizations for quality control assessment of cuffdiff output.

- fpkmSCVPlot: A measure of cross-replicate variability, the squared coefficient of variation is a normalized measure of variance between empirical repicate FPKM values per condition, across the range of FPKM estimates.

Usage

"fpkmSCVPlot"(object,FPKMLowerBound=1, showPool = FALSE)

Arguments

object
An object of class CuffData.
FPKMLowerBound
A lower limit cutoff for FPKM values from which a fit of squared Coefficient of variation (default: 1)
showPool
Logical argument whether to display variability across all replicates independent of condition (TRUE) or the cross-replicate variability for each condition (FALSE)

Value

A ggplot2 plot object with a geom_box layer.

Examples

Run this code
	a<-readCufflinks(system.file("extdata", package="cummeRbund")) #Read cufflinks data and create CuffSet object
	genes<-a@genes #CuffData object for all genes
	csBoxplot(genes)
