[R] adaptive knot placement for splines

Are there any R implementation of adaptive knot placement? No need to be fancy.
Something like stepwise selection by Friedman and Silverman (1989)?

The implementation in polyspline is too specific for lognormal distributions. 

Thanks!

[R] adaptive knot placement for splines

Not TURBO, but BRUTO (bruto() in the mda package) proposed in the discussion
of that paper, or even MARS (mars(), also in mda).
