A popular way to visualise this comparison this is via a volcano plot, where the enrichment of proteins in one condition is towards the right and their de-enrichment (or their enrichment in the other group) is towards the left. The y-axis denotes the p-value of the comparison. Years ago, I wrote an IGOR package called VolcanoPlot, that we have used in our work. For various reasons (see below), I have now ported the package to R.FeaturesThe current version takes an output (or multiple outputs) from MaxQuant, processes the data and can generate:Volcano PlotsMean vs mean plotsPCAText outputs of the analysisIt uses {ggplot2} for graphics and therefore they can be combined easily with other plots.Some examplesThere is full documentation available here. But in brief:The package can be installed in the usual way.# install.packages("pak")pak::pak("quantixed/VolcanoPlotR")There is an example file in the package that can be used for testing.library(VolcanoPlotR)# get the path to the proteinGroups.txt file included in the packagefilepath
