Anyone know of code that will do bilinear interpolation from irregular samples to another set of irregular locations (including points possibly outside the convex hull of the original points)? Akima interpolates to a regular grid AFAICT. I did find one package on CRAN that does this will splines, but I want something simpler. (The particular application requires many repeated calls.)
