The filter.PCA
function applies the feature selection Principal Component Analysis (PCA) to a set of physical measures.
1  filter.PCA(X,nbreVarX_,...)

X 
A matrix where each row is a physical measures. 
nbreVarX_ 
The number of variables which represents each physical measures after the reduction by the PCA. 
... 
Currently ignored. 
The filter.PCA
function is the feature selection PCA. It converts a set of physical measures to another one with less components.
The filter.PCA
function returns an object which can be used with the predict
function to reduce each physical measure. This physical measure can be the same or another one than contained in X.
The value of this function is an object of class filter.PCA
, which is a list with the following components:
mod 
a model of PCA. 
nbreVarX 
number of component to get after the projection by the PCA of a physical measure.
