acepack-1.0.tar.gz:
ace (Alternating Conditional Expectations) and avas (Additivity and
Variance Stabilization for regression) for selecting regression

avas() for S by Rob Tibshirani <tibs@utstat.toronto.edu> and
Friedman & Spector's FORTRAN code for ACE, both from statlib.

[1997/04/23]

date.tar.gz:
Functions for dealing with dates. The most useful of them accepts a
vector of input dates in any of the forms 8/30/53, 30Aug53, 30
August 1953, ..., August 30 53, or any mixture of these.

S original by Terry Therneau <therneau@mayo.edu>.

[1997/04/08]

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>
and based on FORTRAN77 code by Alan Miller
<Alan.Miller@vic.cmis.csiro.au>.

Original data sets from various sources.
[1997/06/27]

oz.tar.gz:
Functions for plotting Australias coastline and state boundaries.

polynom-1.0-2.tar.gz:
A collection of functions to implement a class for univariate
polynomial manipulations.

S original by Bill Venables <Bill.Venables@adelaide.edu.au>.
Packaged for R by Kurt Hornik <Kurt.Hornik@ci.tuwien.ac.at> and
Martin Maechler <maechler@stat.math.ethz.ch>.

snns.tar.gz:
An R interface to the Stuttgart Neural Networks Simulator (SNNS).

Regression spline functions.

Written by Thomas Lumley <thomas@biostat.washington.edu>, based on
the S packages `splines' by Doug Bates <bates@stat.wisc.edu> and
`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.

S original by Terry Therneau <therneau@mayo.edu>.
