RNAseqQA | R Documentation |
RNAseqQA performs the quality analysis of an expression matrix. This function generates different plots over expression data in order to detect possible outliers.
RNAseqQA( expressionMatrix, outdir = "SamplesQualityAnalysis", toPNG = TRUE, toPDF = TRUE, toRemoval = FALSE )
expressionMatrix |
A matrix that contains the gene expression values. |
outdir |
The output directory to store the report of arrayQualityMetrics |
toPNG |
Boolean variable to indicate if a plot would be save to PNG. |
toPDF |
Boolean variable to indicate if a plot would be save to PDF. |
toRemoval |
Boolean variable to indicate if detected outliers will be removed from original data |
A list containing found outliers for each realized test or corrected data if toRemoval is TRUE.
dir <- system.file("extdata", package="KnowSeq") load(paste(dir,"/expressionExample.RData",sep = "")) outliers <- RNAseqQA(expressionMatrix)
