Method R_NX

Calculate the R_NX score from Lee et. al. (2013) which shows the neighborhood preservation for the Kth nearest neighbors, corrected for random point distributions and scaled to range [0, 1].

Usage

# S4 method for class 'dimRedResult'
R_NX(object, ndim = getNDim(object))

Arguments

object

of class dimRedResult

ndim

the number of dimensions to take from the embedded data.
