plotVolcanoDE {RCPA}

Plot volcano plot from Pathway analysis results

Description

Plot volcano plot from Pathway analysis results

Usage

plotVolcanoDE(DEResult, pThreshold = 0.05, useFDR = TRUE, logFCThreshold = 1)

Arguments

DEResult

A data frame with Pathway analysis results. The columns are ID, name, description, p.value, pFDR, size, nDE, score and normalizedScore.

pThreshold

The p-value threshold to use for the horizontal line.

useFDR

logFCThreshold

The logFC threshold to use for the vertical line.

Value

A ggplot2 object.

Examples

library(RCPA)
library(SummarizedExperiment)

affyDEExperiment <- loadData("affyDEExperiment")
agilDEExperiment <- loadData("agilDEExperiment")
RNASeqDEExperiment <- loadData("RNASeqDEExperiment")

p1 <- RCPA::plotVolcanoDE(rowData(affyDEExperiment), logFCThreshold = 0.5) +
    ggplot2::ggtitle("Affymetrix - GSE5281")
p2 <- RCPA::plotVolcanoDE(rowData(agilDEExperiment), logFCThreshold = 0.5) +
    ggplot2::ggtitle("Agilent - GSE61196")
p3 <- RCPA::plotVolcanoDE(rowData(RNASeqDEExperiment), logFCThreshold = 0.5) +
    ggplot2::ggtitle("RNASeq - GSE153873")
