nscancor: Non-Negative and Sparse CCA
Two implementations of canonical correlation analysis
(CCA) that are based on iterated regression. By choosing the
appropriate regression algorithm for each data domain, it is
possible to enforce sparsity, non-negativity or other kinds of
constraints on the projection vectors. Multiple canonical
variables are computed sequentially using a generalized
deflation scheme, where the additional correlation not
explained by previous variables is maximized. nscancor() is
used to analyze paired data from two domains, and has the same
interface as cancor() from the 'stats' package (plus some extra
parameters). mcancor() is appropriate for analyzing data from
three or more domains. See

and Sigg et al. (2007) <doi:10.1109/MLSP.2007.4414315> for more
details.
