Readme

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
