[R] Monotonic interpolation

[Rob Hyndman]

Has anyone got a function for smooth monotonic interpolation of a
univariate function?  I'm after something like the NAG function PCHIM
which does monotonic Hermite interpolation. Alternatively, montononic
cubic spline interpolation.

Please reply directly.
