## Features Plot for generalized Global Ancova

### Description

Produces a plot to show the influence of individual variables on the test result produced by `gGlobalAncova`. The variables can be continuous, binary, categorical, ordinal, or of mixed types.

### Usage

    Plot.features(data, formula.full, formula.red = ~1, model.dat, Set, returnValues = FALSE, ...)

### Arguments

`data` | `data.frame` of variables to be tested in sets (columns=variables); (multi-) categorical variables should be factors, ordinal variables should be ordered factors
`formula.full` | model formula for the full model
`formula.red` | model formula for the reduced model (that does not contain the terms of interest)
`model.dat` | `data.frame` of regressors, containing variables specified in `formula.full` and `formula.red`
`Set` | optional vector of names or indices of variables, defining the set of variables to plot; if missing, all variables in `data` are shown
`returnValues` | shall variable-wise statistics = bar heights be returned?
`...` | graphical parameters passed to `barplot`

### Value

If `returnValues = TRUE`, a vector with the bar heights is returned.
