supplementaryCols function

Supplementary columns

Computes factor scores for supplementary measures (columns).

supplementaryCols(SUP.DATA, res, center = TRUE, scale = TRUE)

Arguments

• SUP.DATA: a data matrix of supplementary measures (must have the same observations [rows] as active data)
• res: ExPosition or TExPosition results
• center: a boolean, string, or numeric. See expo.scale
• scale: a boolean, string, or numeric. See expo.scale

Details

This function recognizes the class types of: epPCA, epGPCA, epMDS, epCA, epMCA, and TExPosition methods. Further, the function recognizes if Hellinger (as opposed to row profiles; in CA, MCA and DICA) were used.

Returns

A list of values containing:

• fjj: factor scores computed for supplemental columns

• djj: squared distances for supplemental columns

• rjj: cosines for supplemental columns
