%description
Construct a Canonical Variate Analysis Biplot via the Generalised Singular
Value Decomposition, for cases when the number of samples is less than the
number of variables. For more information on biplots, see Gower JC, Lubbe
SG, Le Roux NJ (2011) <doi:10.1002/9780470973196> and for more information
on the generalised singular value decomposition, see Edelman A, Wang Y
(2020) <doi:10.1137/18M1234412>.
