+factorization (rNMF).  The rNMF algorithm decomposes a nonnegative high
+dimension data matrix into the product of two low rank nonnegative matrices,
+while detecting and trimming outliers.  The main function is @code{rnmf()}.
+The package also includes a visualization tool, @code{see()}, that arranges
+and prints vectorized images.")
