Description Usage Arguments Value Examples

'build_predictor_dataframe_from_data' extracts a dataframe containing the predictors in a formula, from a larger dataframe.

1	build_predictor_dataframe_from_data(form, data)

`form`	A formula.
`data`	A dataframe.

A dataframe.

Each column of the dataframe is the vector of values associated with a predictor in 'form', as extracted from 'data'.

If the formula has a dot as a predictor (e.g. Y ~ .), then the entire dataframe 'data' is returned minus the column containing the outcome. See the examples.
