Proportion of predictors — predictor

The parameter is used in models where a parameter is the proportion of predictor variables.

predictor_prop(range = c(0, 1), trans = NULL)

Arguments

range: A two-element vector holding the defaults for the smallest and largest possible values, respectively. If a transformation is specified, these values should be in the transformed units.
trans: A trans object from the scales package, such as scales::transform_log10() or scales::transform_reciprocal(). If not provided, the default is used which matches the units used in range. If no transformation, NULL.

predictor_prop() is used in step_pls().
