cardinality

a numeric matrix, e.g. <code>xcoef</code> as returned
  by <code><a rd-options="" href="/link/nscancor?package=nscancor&version=0.6" data-mini-rdoc="nscancor::nscancor">nscancor</a></code>


Computes the cardinality (the sum of non-zero elements) of
each column of the matrix $w$.


This package implements two algorithms for canonical correlation
analysis (CCA) that are based on iterated regression
steps. By choosing the appropriate regression algorithm for each data
modality, 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 the 'cancor' function from the 'stats' package (plus some extra
parameters). 'mcancor' is appropriate for analyzing data from three or more
domains.
