QCplots: Quality Control visualizations

In gofflab/cummeRbund-BioC-Bridge: Analysis, exploration, manipulation, and visualization of Cufflinks high-throughput sequencing data.

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

## S4 method for signature 'CuffData'
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)
