Description: High-dimensional visualization methods for data envelopment
    analysis (DEA), gathering in one place techniques that have appeared in the
    literature but remained scattered and largely unimplemented: cross-efficiency
    matrix unfolding, the Porembski network with lambda edges,
    principal component analysis biplots, multidimensional-scaling
    colour-plots, self-organizing maps, the Costa bi-dimensional efficient
    frontier, parallel coordinates, radar charts, panel-data trajectory biplots,
    peer and reference networks, and a set of descriptive plots. The package is
    built around a single validated dea_data() object and uses the 'Benchmarking'
    package as its DEA engine. The implemented methods draw on a body of
    literature; representative references include Doyle and Green (1994)
    <doi:10.1057/jors.1994.84>, Porembski, Breitenstein and Alpar (2005)
    <doi:10.1007/s11123-005-1328-5> and Bana e Costa, Soares de Mello and Angulo
