clps (Constrained Local Polynomial Smoothing)

Release 0.1, released on 16 July 2004

This is an R package that contains FORTRAN77 code and R routines for constrained local polynomial smoothing. It depends on the R package quadprog that is available from CRAN.

The package is available in the following formats:

As a source file clps_0.1.tar.gz, suitable for installation from source.
As a compiled clps_0.1.zip file for binary installation under MS Windows. This binary version was created with R 1.8.1 (specifically, Version 1.8.1 (2003-11-21), ISBN 3-900051-00-3).
As a compiled clps_0.1.zip file for binary installation under MS Windows. This binary version was created with R 1.9.1 (specifically, Version 1.9.1 (2004-06-21), ISBN 3-900051-00-3).

This package is based on

and I decided to distribute it in the hope that it may also be useful to others. Hence, this software is provided "as is" without any expressed or implied warranty.
