R-alpha: Re: R-beta: mlbench-0.1 --- machine learning benchmark problems

I've made a package from some benchmark datasets for use with R and

Here's the Index entry:

mlbench-0.1.tar.gz:
	A collection of artificial and real-world machine learning
	benchmark problems, including, e.g., the boston housing
	data from the UCI repository.

	Written/packaged by Fritz Leisch <Friedrich.Leisch@ci.tuwien.ac.at>
	Original data sets from various sources.

This (naturally) includes some data files ... hence you have to do
some parts of the installation manually, see the INSTALL file for
details (IMHO R has no clear concept for data: one flat directory is
certainly not sufficient).

Just for the sake of completeness (for those who don't use our Debian
GNU/Linux packages).  We have ``meanwhile'' (before we agree on an
official R file standard) simply introduced a one-level hierarchy in
RHOME/data.  The data files that come with the base distribution are in
RHOME/data/base, the new ones in RHOME/data/mlbench etc.

This change requires nothing but changing RHOME/cmd/filename, e.g. as
below.

What would also be nice is to have `make libs' install the data as well
to RHOME/data/$LIBNAME.
