[R] Monotonic regression in R??

[M. Edward (Ed) Borasky]

Is there R code somewhere for monotonic regression? I have some functions
(computer response time curves) that are guaranteed by theory to be monotonic,
and some experimental data where they are not. What I'd like to do is plot a
smooth monotonic curve through the experimental points. There is no closed form
expression for the curve, although there is a recursive difference equation
formulation in some simple cases, so ordinary nonlinear regression is not the
answer. I have Hardle's book (the title of which escapes me at the moment)
which gives the algorithm, so I can code it if it doesn't exist already, but I
was hoping it was already done.
