supplementalProjection: Supplemental projections.

In ExPosition: Exploratory Analysis with the Singular Value Decomposition

Description

Performs a supplementary projection across ExPosition (and related) techniques.

Usage

supplementalProjection(sup.transform = NULL, f.scores = NULL, Dv = NULL, 
scale.factor = NULL, symmetric = TRUE)

Arguments

sup.transform	Data already transformed for supplementary projection. That is, the output from: caSupplementalElementsPreProcessing, mdsSupplementalElementsPreProcessing, pcaSupplementaryColsPreProcessing, or pcaSupplementaryRowsPreProcessing.
f.scores	Active factor scores, e.g., res$ExPosition.Data$fi
Dv	Active singular values, e.g., res$ExPosition.Data$pdq$Dv
scale.factor	allows for a scaling factor of supplementary projections. Primarily used for MCA supplemental projections to a correction (e.g., Benzecri).
symmetric	a boolean. Default is TRUE. If FALSE, factor scores are computed with asymmetric properties (for rows only).

Value

A list with:

f.out	Supplementary factor scores.
d.out	Supplementary square distances.
r.out	Supplementary cosines.

It is preferred for users to compute supplemental projections via supplementaryRows and supplementaryCols. These handle some of the nuances and subtleties due to the different methods.
