acepack-1.0.tar.gz:

ace (Alternating Conditional Expectations) and avas (Additivity and
Variance Stabilization for regression) for selecting regression
transformations.

Written by Thomas Lumley <thomas@biostat.washington.edu>, based on
avas() for S by Rob Tibshirani <tibs@utstat.toronto.edu> and
Friedman & Spector's FORTRAN code for ACE, both from statlib.

leaps-1.0.tar.gz:

This package performs an exhaustive search for the best subsets of
a given set of potential regressors, using a branch-and-bound
algorithm, and also performs searches using a number of less
time-consuming techniques. It is designed to replace the "leaps()"
command in S.

Packaged for R by Thomas Lumley <thomas@biostat.washington.edu>

`safe.predict' by John Chambers and Trevor Hastie.
[1997/04/23] [1997/07/29]

survival-4R0.1.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 add-on package, but most of the functionality is already
available. The ratetable and cohort expected survival functions
still don't work.

Requires the splines package.
