Generalized version of ovl_knn (Rvalue).

Calculate distribution overlap by KNN (K-Nearest neighbor) This function is the original implementation of Rvalue. It works with more than 3 classes. The behavior of function is exactly the same as ovl_knn.

Rvalue(ds, cl, k = 5)

Arguments

ds	A numeric vector.
cl	An integer vector designating classes.
k	An integer. Number of k in KNN

Examples

ds = c(rnorm(100, 0), rnorm(100, 1), rnorm(100,2))
cl = c(rep(0,100), rep(1,100), rep(2,100))
Rvalue(ds, cl, k=5)
