This class is used for objects that are returned by <code><a rd-options="klausuR:klausur" href="/link/klausur?package=klausuR&version=0.12-14&to=klausuR%3Aklausur" data-mini-rdoc="klausuR:klausur::klausur">klausur</a></code>.

classes

A set of functions designed to quickly generate results of a multiple choice
test. Generates detailed global results, lists for anonymous feedback and
personalised result feedback (in LaTeX and/or PDF format), as well as item
statistics like Cronbach's alpha or disciminatory power. 'klausuR' also
includes a plugin for the R GUI and IDE RKWard, providing graphical dialogs for
its basic features. The respective R package 'rkward' cannot be installed
directly from a repository, as it is a part of RKWard. To make full use of this
feature, please install RKWard from <https://rkward.kde.org> (plugins are
detected automatically). Due to some restrictions on CRAN, the full package
sources are only available from the project homepage.
