I never had seen spline() inside some nls()/nlme() function. Are you sure
that this fit is possible? Splines makes a lot or successive local
polynomial fits, so they need a lot of parameters. I don't think that is
possible a good spline fit with only four parameters. In this case you could
use loess() or locfit() in locfit library.
