[R] Bivariate interpolation

[Miha STAUT]

Hello,

Is there any other bivariate pointwise interpolation command besides akima's 
interpp? I tried to search through the J. Baron's page without luck.

The problem is that I have got regularly spaced data (in x and y) what is 
not acceptable for interpp.

I am not very much interested in the method of interpolation as the data are 
dense and the error would not be to high.

Thanks in advance, Miha
