Lots of questions! Kriging in geostatistics software often uses rather
peculiar approximations to the exact theory, and `data' cannot be
anisotropic (but models can).
There is kriging in packages spatial, sgeostat and fields, at least, as a
quick look at the FAQ would have shown you.
It is unlikely that an R package will provide you with C/C++ code that is
independent, but some are based on such code. If you want independent
code, you should look elsewhere (e.g. GSLIB).
