Calculate distances to k-th nearest neighbor for each point
Usage
tidy_knn_dist(data, k = 4, cols = NULL)
Arguments
- data
A data frame or matrix
- k
Number of nearest neighbors (default: 4)
- cols
Columns to include (tidy select).
If NULL, uses all numeric columns.
Value
A tibble with columns .obs_id (observation identifier),
knn_dist (distance to k-th nearest neighbor), and rank
(rank of the k-NN distance).
Examples
# \donttest{
knn <- tidy_knn_dist(iris[, 1:4], k = 5)
# }
