 Hi, 
I am new in R and trying to implement an algorithm which makes ordinary kriging by using gstat library and the predict method. 
I use the predict method as following: 
First, I create an object g: 
g <- gstat(id="tec", formula=TEC ~ 1, data=data) ## Create gstat object called g 
And then I use this object in the predict. 
p <- predict.gstat(g, model=mod, newdata=predGrid, nsim=0) 

My problem is that instead of Ordinary kriging, when I run the algorithm I get: Inverse distance weighted interpolation. 
Why is that? What am I missing or doing wrong? 

Thanks in advance 
Dimitris
