neighbors

Number of neighbors

Description

The number of neighbors is used for models (parsnip::nearest_neighbor()), imputation (recipes::step_knnimpute()), 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.
`trans`	A `trans` object from the `scales` package, such as `scales::log10_trans()` or `scales::reciprocal_trans()`. 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.

Examples

neighbors()
