I have a data set of
x,y,z data and I'd like to do a bicubic interpolation. x and y are spatial coordinates and z is a temperature.
Below there are two images. The first one is a (gnuplot) plot of my dataset and the second one is an interpolated version (
set pm3d interpolate 10,10).
Now I'd like to do this interpolation in R but I want a matrix of values as result and not a plot. The
climates package seemed to provide this in R, but it does not work in R 2.13 anymore.
Is there another way/package to interpolate in R the way I want?
