plot.raggr {RankAggreg}

Plot function for raggr object returned by RankAggreg or BruteAggreg

Description

Plots individual ordered lists with the corresponding solution. Optionally, naive average rank aggregation can be added.

Usage

## S3 method for class 'raggr'
plot(x, show.average = TRUE, show.legend = TRUE, colR="red", ...)

Arguments

x

raggr object returned by RankAggreg

show.average

boolean if average aggregation to be plotted

show.legend

boolean if the legend is to be displayed

colR

specifies the color for the resulting list

...

additional plotting parameters

Details

The function plots individual lists and the solution using ranks only (weights are not used at any time). Optional average rank aggregation can be performed and visualized. Average rank aggregation is a simple aggregation procedure which computes the average ranks for each unique element accross and orders them from the smallest to the largest value.

Value

Nothing is returned
