In isobar: Analysis and quantitation of isobarically tagged MSMS proteomics data

Description

Correct peptide ratios with protein ratios from a separate experiment.

Usage

correct.peptide.ratios(ibspectra, peptide.quant.tbl, protein.quant.tbl,
         protein.group.combined, adjust.variance = TRUE,
         correlation = 0, recalculate.pvalue = TRUE)

Arguments

ibspectra	IBSpectra object.
peptide.quant.tbl	Calculated with peptideRatios.
protein.quant.tbl	Calculated with proteinRatios.
protein.group.combined	ProteinGroup object generated on both PTM and protein data.
adjust.variance	Adjust variance of ratios.
correlation	Assumed correlation between peptide and protein ratios for variance adjustment.
recalculate.pvalue	Recalculate p-value after variance adjustment.
