Description Usage Arguments Value Examples

Description

plot_ibaq plots a scatter plot of the iBAQ intensities versus the LFQ fold changes.

# load data

# Test for differential enriched proteins
se <- import_MaxQuant(proteins, exp_design,
    filter = c("Reverse", "Contaminant"))
processed <- process(se, fun = "MinProb")
