help.search()
on my machine turns up only:
mono.con(mgcv) Monotonicity constraints for a cubic
regression spline.
smooth.monotone(fda) Monotone Smoothing of Data
pmreg(ftnonpar) Piecewise monotone regression with taut
strings
backSpline(splines) Monotone Inverse Spline
isoreg(stats) Isotonic / Monotone Regression
so you should find something of use in packages mgvc, fda, ftnonpar, splines
or stats (.loaded by default)

Hi all,
I'm looking for smooth monotone estimation packages, preferably using splines.
I downloaded the 'cobs' package and intend to use it, but since it offers only
quadratic splines based on L1 minimization, I'd like to compare its performance to
that of a more 'mainstream' cubic-spline, L2-norm minimizing spline. Preferably a
smoothing spline.
Does anyone know of such code existing anywhere? Or another smooth monotone
alternative?
Thanks in advance,
