[R] S intrp function

[Don Isgitt]

Hi.

I am trying some S-Plus scripts that I used a few years ago on R. Many 
things have worked flawlesly and I am very impressed with the work the 
developers have done. (As I remember, the license fee on S-Plus at that 
time was ~$4500 per seat (AIX) ouch!!) So, thank you.

My question relates to the intrp function, which takes irregularly 
spaced xyz data and produces a regular xyz grid suitable for contouring 
or imaging. I have not found the equivalent function in R; have I missed 
it or is there some other preferred method to accomplish this.

Thank you very much.
