depthR - Multivariate Depth Functions for General Dimension
Efficient computation of multivariate statistical depth
functions in arbitrary dimension d. Implements Mahalanobis
depth, Tukey (halfspace) depth, Liu simplicial depth (via
adaptive Monte Carlo), projection depth, and spatial depth.
Provides depth-based medians, central regions, outlier
detection, and depth-depth plots. 'C++' backends via 'Rcpp' and
'RcppEigen' ensure performance at large n and d. References:
