### Arguments

`x` | An object of class `exprSet-class` which has been created by the function `vsn`.
`what` | Character, should either be "factors" or "offsets".
`xlab` | Character, label for the x-axis.
`ylab` | Character, label for the y-axis.
`...` | Further arguments that get passed to plot.default.
