kern specifies the base kernel (by default Gaussian) used in
lpc ; kernd is the corresponding multivariate product
kernel. kdex is a pointwise multivariate kernel density estimator.
distancevector makes use of function vdisseuclid from R package hopach (but that package does not need to be loaded). enorm is the Euclidean norm.
