[R] Find inflection points using smooth.spline

Is there any way to identify or infer the inflection points in a smooth
spline object?  I am doing a comparison of various methods of time-series
analysis (polynomial regression, spline smoothing, recursive partitioning)
and I am specifically interested in obtaining the julian dates associated
with the inflection points inferred by the various models.
