ppform

The ppform of a polynomial spline of order provides a description in terms of its breaks and the local polynomial coefficients of its pieces.

For example, a cubic spline is of order 4, corresponding to the fact that it requires four coefficients to specify a cubic polynomial. The ppform is convenient for the evaluation and other uses of a spline.
