sits_formula_logref: Define a loglinear formula for classification models

Description

A function to be used as a symbolic description of some fitting models such as svm and random forest. This function instructs the model to do a logarithm transformation of the input values. The `predictors_index` parameter informs the positions of `tb` fields corresponding to formula independent variables. If no value is given, the default is NULL, a value indicating that all fields will be used as predictors.

Usage

sits_formula_logref(predictors_index = -2:0)

Arguments

predictors_index

Index of the valid columns whose names are used to compose formula (default: -2:0).

Value

A function that computes a valid formula.
