+for missing value estimation is included for comparison.  BPCA, PPCA and
+NipalsPCA may be used to perform PCA on incomplete data as well as for
+accurate missing value estimation.  A set of methods for printing and plotting
+the results is also provided.  All PCA methods make use of the same data
+structure (pcaRes) to provide a common interface to the PCA results.")
