# Generating volcano scatterplot

This might look a very silly question to many of you but please answer.

I am interested in generating a volcano plot for my dataset, which has four columns and all values are in log2. column 1 has name while column 2, 3, 4 has values in treated, untreated states and fold change.

I am intrested in generating scatter plot from these values with marking outliers at 2 fold.

I am bit confused and puzzled with the command in R as it is asking more than one parameter like p-value and things which I do not have.

drawVolcanoPlot(M,p,m=1,p.cut=0.05,p.transform=log10,ylab=NULL,colramp=NULL,na.rm=TRUE,...)

Kindly help me in generating this scatterplot with my dataset.

Solutions in python are also welcome.

Thank you for your time and consideration.
