parse_n_features: Parsing features

In UBC-MDS/punisheR: Feature Selection Using AIC and BIC

Description

Parse n_features for forward and backward selection. Handles two cases:

• if n_features is an integer, ensure it lies on (0, total).

• if n_features is a float, ensure it lies on (0, 1).

Usage

parse_n_features(n_features, total)

Arguments

n_features	A numeric value passed to forward or backward selection. Can be a float or integer.
total	Total features in the data (equivalent to number of columns in X)

Value

Number of features to select. If initial n_features lies on (0, total_features), it will be returned 'as is'. If n_feature is passed in as a proportion with range (0,1), it will be converted to an integer representing proportion with respect to the total number of features.
