The number of neighbors is used for models (parsnip::nearest_neighbor()),
imputation (recipes::step_impute_knn()), and dimension reduction
(recipes::step_isomap()).
neighbors(range = c(1L, 10L), trans = NULL)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.
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.
A static range is used but a broader range should be used if the data set is large or more neighbors are required.
