Title: Assessment and Evaluation of Formations in United
Version: 0.4
Description: United is a software tool which can be downloaded at the following website http://www.schroepl.net/pbm/software/united/. In general, it is a virtual manager game for football teams. This package contains helpful functions for determining an optimal formation for a virtual match in United. E.g. knowing that the opponent has a strong defensive it is advisable to beat him in the midfield. Furthermore, this package contains functions for computing the optimal usage of hardness in a game.
