 leaps1.0.tar.gz:

This package performs an exhaustive search for the best subsets of
a given set of potential regressors, using a branchandbound

timeconsuming techniques. It is designed to replace the "leaps()"
command in S.
Packaged for R by Thomas Lumley <thomas@biostat.washington.edu>

A collection of functions to implement a class for univariate
polynomial manipulations.
S original by Bill Venables <Bill.Venables@adelaide.edu.au>.

`safe.predict' by John Chambers and Trevor Hastie.
[1997/04/23] [1997/07/29]
 survival4R0.1.tar.gz:

Functions for survival analysis. This ``port'' is not complete yet,
because it requires a few changes to the R system itself rather than
the addon package, but most of the functionality is already
available. The ratetable and cohort expected survival functions
still don't work.
Requires the splines package.
