input_data_checks: Check Data Input

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

Description

Checks that input data for 'forward()' and 'backward()' functions are the correct format. Specifically looks for:

• X and y are appropriate dimensions (both same number of observations)

• X is a 2D numeric vector and y is a 1D numeric vector

Usage

input_data_checks(X, y)

Arguments

X	input for either X_train or X_val. Expected to be a 2D numeric matrix.
y	input for either y_train or y_val. Expected to be a 1D numeric matrix. If 'y' is a character string AND X is a dataframe, it will be extracted from X.

Value

list X matrix (If X is a dataframe when input, it will be converted into a matrix. Otherwise, if all of the checks pass, it will be returned 'as is'.) y 'as is' or extracted from X (if y was a character string on input.
