[R-sig-Geo] difrrence between regression kriging&residual kriging

[Saman Monfared]

Hi
I'm very confused about the concepts of regression kriging ,kriging
with external drift
(KED) and residual kriging.because In various articles these are
defined differently.
could you give me a  download-able good source about these methods.
 Do these methods can be generalized to cokriging??for
example(residual cokriging-regression cokriging,...)
Which packages in R can perform them??
