## class VarSelection

### Description

Class `VarSelection` S4 class (linkHD: integrating multiple heterogeneous datasets) VarSelection is a class to perform variable selection from a DistStatis object.

### Features

1. class to perform variable selection using Linear Regression Biplot onto the Compromise-Subespace

2. This method allow variable selection and classification

### Fields

- Variables return all the selected variables (and the frecuency of selection).

- Coordinates represent the coordenates (Betas coeeficients on LM) of the selected variables.

- VarTable data.frame indicating which table selected variables come from.

- values data.frame contains the R2 or pvalue (fdr) of selected variables (it depends of the Crit used).

### Accesors
