plotting data in non-orthogonal coords.

[...]

It would be nice if one could just plot data given as F(x,y) where
you supply x and y for every data point seperatly so that you dont
need any specific grid.

This is one solution, but it's not exactly what you want:


library(lattice)
u <- row(matrix(0, nrow = 10, ncol = 15))
v <- col(matrix(0, nrow = 10, ncol = 15))
x <- u
y <- .5 * u + .3 * v
z <- log(u + v)
wireframe(z ~ x * y)
