MArrayLM object created with
eBayes() from the
limma package contains the slot
$p.values, which I suppose is used by
volcanoplot() to make the volcano plot. Since the volcano plot has log2FC in the x-axis, I suppose
volcanoplot() also gets the log2FC values from the
MArrayLM object, but how to extract the log2FC values from the
MArrayLM object myself?
