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. Don p.s. I am not subscribed to this list, so an email reply would be appreciated.

There is function `interp' in library(akima). Maybe this is what you're looking for? -roger _______________________________ UCLA Department of Statistics rpeng at stat.ucla.edu http://www.stat.ucla.edu/~rpeng

Try package akima, interp() or variants should do what you need.
Thank you very much. Don
