[R] Z aware interpolation

[Monica Palaseanu-Lovejoy]

Hello again,

There is any package which does Z aware (real 3D) interpolations? 
It can be any method (IDW, kriging or spline) but it should take into 
consideration not only x and y coordinates for interpolation, but 
also z coordinate. I looked into different packages but it seems i 
didn't find the right one.

The ultimate goal is to import the output into a GIS (Geographical 
Information System) for further analysis.

Alternatively, maybe you know a source for codes for normal IDW 
(Inverse Distance Weight) interpolation (i mean the one which 
takes into consideration only x and y coordinates) so i can try to 
modify it to take into consideration z values as well. I am not sure 
it will work, or i can do it - but it worth a try - of course if this is not 
already done. 

Thanks,

Monica
