# A graphical user interface for the package rankFD

### Description

This function provides a graphical user interface for calculating rank-based statistical tests in general factorial designs.

### Usage

1 |

### Details

The function produces a GUI for the calculation of the test statistics and
for plotting. Data can be loaded via the "load data" button. The formula
and the significance level alpha (default: 0.05) need to be specified.
One can choose between two different null hypotheses (*H_0^F* and *H_0^p*, see the details
to `rankFD`

) to be tested as well as
weighted or unweighted effects as discussed in Brunner et al. (2016) (*r_i* and *p_i* in
their notation).
If the plot option is chosen, an additional window opens containing
information on the plots.
