# Calculate and plot the k-Nearest Neighbor Distance

### Description

Fast caclulation of the k-nearest neighbor distances in a matrix of points.
The plot can be used to help find a suitable value for the
`eps`

neighborhood for DBSCAN. Look for the knee in the plot.

### Usage

1 2 | ```
kNNdist(x, k, ...)
kNNdistplot(x, k = 4, ...)
``` |

### Arguments

`x` |
the data set as a matrix or a dist object. |

`k` |
number of nearest neighbors used (use minPoints). |

`...` |
further arguments are passed on to |

### Details

See `kNN`

for a discusion of the kd-tree related parameters.

### Value

`kNNdist`

returns a numeric vector with the distance to its k nearest
neighbor.
