[R] Access to particular predict value

[Toni Viúdez]

Hi everybody:

I just generate interpolation maps with differents methods, like IDW and 
kriging, and now i want to compare the predict values versus real, and i 
don't who is the commant to do it. I want for example, if I pass from console 
the coordinates of a place, return me the predict value.
Could anybody tell me how should do?.

Thanks in advance
