...quot;svd" or "als" (alternating least squares), for specifying which of the two approaches above should be used. *included in the package is svd.als, an efficient rank-restricted svd algorithm that can exploit sparsity and other special structure, and accept warm starts. * a function biScale is provided, for centering and scaling both rows and columns of matrix to have means zero and variance 1. The centering and scaling constants are stored on the object. For sparse matrices with centering, the centered object is stored in "SparseplusLowRank" form to preserve its special s...
