Dear R users: before I try to undertake my own rewrite, has anyone already written a contour function that does not require a regularly spaced grid, preferably plot.contour(x,y,z,...)? (it would be nice if it were based on loess() and plot()? further annotations, changes, etc., would then be easier.)
The akima function in the package by the same name provides that facility.
