### Usage

    plotVolcano(x, p.value = -log10(0.001), labels, show.effect = FALSE)

### Arguments

`x` | An `ExWAS` object which effect will be ploted.
`p.value` | (default `"-log10(0.001)"`) Threshold for P-Value.
`labels` | (optional) Character vector with the labels for each exposure. It must be labeled vector.
`show.effect` | (default `FALSE`) Applyes an exponential transformation on the effects of the exposures.

### Value

An object of class `ggplot`.
