R package lpridge – with lpepa() and lpridge()

• Original S-plus interface and Fortran code by Burkhard Seiffert, Biostat Uni Zurich, April 1995.

• The port of the lpepa and lpridge to R has been done by Martin Maechler, see DESCRIPTION.

• A “link” (to Martin Maechler’s files) of the original fortran routines and S-plus interface are in the R-forge repository https://r-forge.r-project.org/scm/viewvc.php/pkg/lpridge/?root=curves-etc (source via svn checkout svn://svn.r-forge.r-project.org/svnroot/curves-etc/pkg/lpridge )

in sub directory

Orig/

but not in the package sources (lpridge_<ver>.tar.gz) on CRAN.

Short History:

• MM did get the original sources in April 1995 as shar files, separately for lpepa and lpridge

• found there were too many communalities to keep these separate.

• one of the relatively first CRAN packages, May 18, 2001:

  lpridge_1.0-0.tar.gz

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
