2D interpolation

Dear list I am looking for a function that interpolate data points z in the x,y-plane. For the one-dimensional case this would be a "natural cubic spline". Is there a package where I find a function for "natural thin plate splines" for interpolation? I found in the akima package the function interp. But this is not a thin plate spline interpolation.
RSiteSearch("thin plate spline")
pulls up:

as second hit for me. Try Tps() in the fields package.
