bgCorr: Background noise correction of expression data

In Biopeak: Identification of Impulse-Like Gene Expression Changes in Short Genomic Series Data

Description

This helper function performs a background noise correction before subjecting the corrected matrix to the peakDetection function. Genes with an expression lower than the 5

Usage

bgCorr(exprmat)

Arguments

exprmat

A numeric matrix with time-series expression data with variables as rownames.

Value

Returns background noise corrected expression matrix.

# Example based on the heat-shock dataset
data(heat)
heat = as.matrix(heat)
# Execute the bgCorr function
exprmat_corrected <- bgCorr(heat)
