neighbors: Number of neighbors

Description

The number of neighbors is used for models (parsnip::nearest_neighbor()), imputation (recipes::step_impute_knn()), and dimension reduction (recipes::step_isomap()).

Usage

neighbors(range = c(1L, 10L), 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.

Details

A static range is used but a broader range should be used if the data set is large or more neighbors are required.
