R help - Jan 2019 - Fit CMARS with R possible (Packages) ?

Dear R-experts,

We can fit MARS regression using the packages "earth" and/or
"mda" or others packages.
However, I am wondering if it is possible to fit a CMARS (Conic multivariate
adaptive regression splines) using R ?
I have googled "conic MARS with R software", I did not get anything,
so Google is not my friend anymore !

If you have any solution, would be highly appreciated.

Best,

rseek.org might be a better place to search if you haven't tried t
herealready. However, my minimal effort there did not turn up any R
software.  Maybe you can do better.

Hi,

Like Bert, I was not able to find anything built in R.

It is possible that CMARS has not yet been implemented in R, or may be in
development but not yet ready for release.

I found several references to the use of MOSEK (https://www.mosek.com) along
with MATLAB, but both are commercial products.

The MOSEK developers appear to have an Rmosek interface package:

  https://docs.mosek.com/8.1/rmosek/index.html

which provides access to the MOSEK functionality via R. But, it requires
MOSEK...

Perhaps others with more refined knowledge will jump in. It might also be
reasonable to consider contacting what appears to be a small-ish group of common
authors that I came across in the search who have described the methodology
(e.g. Taylan or Yerlikaya-?zkurt) to see if they are aware of any R
implementations.

Regards,

Marc Schwartz
