Hi, I'm using from little time to analyze my microarray data. After using eBayes() function to compute the odds ratio for my genes now i want to draw a volcano plot showing my data. I've used the volcanoplot() function as follow: > volcanoplot(fitNorm, highlight=500, names=fitNorm$genes$ID) and I get a volcano plot with 500 gene highlighted, each one with his name... So the resulting graph is quite confused! I want to know if there is a way to obtain a volcano plot with dots rapresenting my top-500 genes designed, for example, in a different color (but without names labels). Thanks! Edo
