There are several test scripts with my DSE library available at
<http://www.bank-banque-canada.ca/pgilbert>. (Please don't make the mistake of
trying to install the version on CRAN - it installs with R 0.61 but there have
been a lot of changes to R since then.)

The library calls compiled fortran for the really loop intensive core
calculations, but this is fairly representative of R. With R (up to 0.64.2) the
shortest set of tests (test.dse.lite) takes 7-8 minutes on a Sparc Ultra 10.
(Splus 3.3 takes 4-5 minutes.) There are several longer tests, including some
curvature calculations which take many hours. (In some of the more complicated
tests there are a few things which do not work in R, but most things do.) I use
generic functions a lot, and also use a set of "kernel" functions to help
protect my code from ongoing changes in R and S. This means that function
dispatch gets heavily exercised.

Attached below are results from the light and medium test for 0.64.2 and the
development snapshot (0.65) from a month ago (June 11). These show the timing at
the bottom of each test. As I recall I had to make a small fix to 0.64.2 in
order to get things working - but I don't remember what it was. If you have a
problem, send me the error message and it will jog my memory. I don't see a
large difference in the times, but I don't know if hashing was already in the
snapshot I have.

The pending changes in the ts library will have some affect on what has to be
attached to run the tests. Hopefully I will get a chance to test the library
today or tomorrow.

I would like to see the results of your testing, even if you decide not to use
these test.
