probeR.parallel.plot {ProbeR}R Documentation

Parallel coordinate plot of summary value and probe level data

Description

Parallel coordinate plot of summary value and probe level data is very useful to explore the probe level data with summary value gene by gene.

Usage

probeR.parallel.plot(affy.ID,data.summary, data.probe)

Arguments

affy.ID affymetrix id
data.summary the summary values from the function exprs
data.probe the normalized probe level data. They should be normalized using the same method for the summary values. Also they should be the same probe level data calculating the summary values. If the user use RMA with PM values, this should be only PM values.

data(affybatch.example)
eset<-expresso(affybatch.example,bg.correct=FALSE,normalize.method="quantiles",pmcorrect.method="pmonly",summary.method="medianpolish")
data.summary<-exprs(eset)
probe.norm<-normalize.AffyBatch.quantiles(affybatch.example,type="pmonly")
data.probe<-log(probes(probe.norm),base=2)
probeR.parallel.plot("D78156_at",data.summary,data.probe)
