[R] Replace missing values in spatial design using moving average

[Arnaud Dowkiw]

Dera R helpers,

I have a (x,y,z) data file where x and y are spatial coordinates and z a 
variable. I have some missing values in the z column and I would like to 
replace them with an optimized estimation from the neighbour cells. I could 
not find any function in R to do that. Is anybody aware of such function ? 
Maybe someone knows how to implement the Papadakis method in R...
Thanks for your help,

Arnaud DOWKIW
