## Function to visualise machine learning results using density plot

### Description

`xMLdensity` is supposed to visualise machine learning results using density plot. It returns an object of class "ggplot".

### Usage

    xMLdensity(
    xTarget,
    displayBy = c("All", "GS", "GSN", "GSP", "NEW"),
    x.scale = c("sqrt", "normal"),
    font.family = "sans",
    signature = TRUE
    )

### Arguments

`xTarget` | an object of class "xTarget" or "dTarget" (with the component 'pPerf')
`displayBy` | which targets will be used for displaying. It can be one of "GS" for gold standard targets, "GSN" for gold standard negatives, "GSP" for gold standard positives, "NEW" for putative/new targets (non-GS), "All" for all targets (by default)
`x.scale` | how to transform the x scale. It can be "normal" for no transformation, and "sqrt" for square root transformation (by default)
