plot_kNN_mean_dist: Plot distance to kNN
In nlhuong/buds: Bayesian Unidimensional Scaling (BUDS)

Computes average distance to K nearest neighbours and plots the values for every data point ordered according to coordinates computed with BUDS.

1 2	plot_kNN_mean_dist(D, tau, K = NULL, color = "blue", color_label = "Covariate", error_bars = FALSE)

`D`	A dissimilarity matrix.
`tau`	A numeric vector of latent 1D coordinates.
`K`	[Optional] An integer indicating the number of points to include in the neighbourhood. If not specified one tenth of the total number of data points is used.
`color`	[Optional] A vector or a character string for point colors.
`color_label`	[Optional] A character string for the color label.
`error_bars`	[Optional] Whether to include error bars in the plot.
