`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).
