Number of neighborsSource:
The number of neighbors is used for models (
recipes::step_impute_knn()), and dimension reduction
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.
transobject from the
scalespackage, such as
scales::reciprocal_trans(). If not provided, the default is used which matches the units used in
range. If no transformation,
A static range is used but a broader range should be used if the data set is large or more neighbors are required.
