R help - Sep 2005 - Access to particular predict value

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

If you would still like help from this list, please provide a very 
simple reproducible example to help what you tried that didn't quite 
work.  There are several functions that use inverse distance weighting 
(IDW) and kriging for geostatistical computations.

p.s.   PLEASE do read the posting guide! 
"www.R-project.org/posting-guide.html".  I believe that people who use
the posting guide generally get better answers quicker, because it is 
easier for others to understand what they want.
