Preprocessing of the columns of the table for STATIS.

1	mpSTATIS.columnPreproc(data, column.preprocess = 'None')

`data`	Data Matrix
`column.preprocess`	String option with the following options: 'None' (default),'Center','1Norm', 'Center_1Norm' and 'Z_Score'

Column Preprocessing is the second preprocessing step in STATIS. The only combination of Column Preprocessing allowed is Column Center plus 1 Norm.Besides this combination, all other column preprocessing options are done independently.

If you need to create the Group Matrix into a design matrix, you can use makeNominalData which was developed by Derek Beaton.

A matrix of the same dimensions as X, which is the result of the column preprocessing step chosen.
