SharedNeighborDistance: Shared Neighbor Distance

Description

Calculates the Shared Neighbor Distance

Usage

SharedNeighborDistance(Data, k = 5, NThreads = NULL, ComputationInR = FALSE)

Value

Distance

[1:n,1:n] symmetric matrix, containing the distanes of the cases (rows) for the given data

Arguments

Data

[1:n,1:d] matrix with n cases, d variables

k

Integer defining the number of nearest neighbors

NThreads

Number of threads in parallel computation.

ComputationInR

Boolean (Default ComputationInR = FALSE). If FALSE, do computation in Rcpp, else in R (very slow).
