extract.features: Feature Extraction

Description

Extracts features from models that have been previously fit.

Usage

extract.features(x, dat = NULL, grp = NULL, method, model.features = FALSE, bestTune = NULL, f, comp.catch = NULL)

Arguments

x
Previously fitted model
dat
Numeric variable data used for fitted models (In appropriate format)
grp
Vector of training classes
method
String indicating the INDIVIDUAL model being extracted from
model.features
Logical argument dictating if features selected determined by models instead of user determined number of features.
bestTune
If model.features = TRUE, must provide the parameter at which to extract features from the model.
f
Number of features to subset
comp.catch
An internal check for plsda models. If the optimal model contains only 1 component, the ncomp paramter must be set to 2 for the model. However, features are still extracted only from the first component.
