Hi all,

I generated a volcano plot with CummeRbund. Now I want to label the significant genes with the gene names. How can this be done?

Thanks!

Just the basic command

csVolcano(genes(object = cuff_data), x = 'Sample1', y = 'Sample2', alpha=0.05, showSignificant=TRUE)

This is the basic code:

csVolcano(object, x, y, alpha=0.05, showSignificant=TRUE,features=FALSE, xlimits = c(-20, 20), ... )

So, why is yours different? Why do you use

csVolcano(genes(cuff_data, ...

Also, perhaps include features=false if you didn't set the feature-level data?

Did you already try using basic R plotting functions like arrows and text?
