Description :
Two methods for performing a constrained principal component analysis
(PCA), where non-negativity and/or sparsity constraints are enforced on
the principal axes (PAs). The function \'nsprcomp\' computes one
principal component (PC) after the other. Each PA is optimized such
that the corresponding PC has maximum additional variance not explained
by the previous components. In contrast, the function \'nscumcomp\'
jointly computes all PCs such that the cumulative variance is maximal.
Both functions have the same interface as the \'prcomp\' function from
the \'stats\' package (plus some extra parameters), and both return the
result of the analysis as an object of class \'nsprcomp\', which inherits
from \'prcomp\'. See
