Default Bug#618789: ITP: r-cran-stabledist -- Stable distribution functions

Package: wnpp
Owner: Dirk Eddelbuettel <edd@debian.org>
Severity: wishlist

* Package name : r-cran-stabledist
Version : 0.6-0
Upstream Author : Diethelm Wuertz and Martin Maechler
* URL or Web page : http://cran.r-project.org/web/packages/stabledist/index.html
* License : GPL (>= 2)
Description : Stable distribution functions

This is code that was factored out of the existing package fBasics (aka
r-cran-fbasics) which will now depend on it. Martin Maechler, an R Core
member, refactored and improved it.

In case you want to read up on stable distributions, you can start here at
http://en.wikipedia.org/wiki/Stable_distribution

The debian/control file is

Source: r-cran-stabledist
Section: gnu-r
Priority: optional
Maintainer: Dirk Eddelbuettel <edd@debian.org>
Build-Depends: debhelper (>= 7.0.0), r-base-dev (>= 2.12.2), cdbs
Standards-Version: 3.9.1
Homepage: http://www.rmetrics.org

Package: r-cran-stabledist
Architecture: any
Depends: ${shlibsepends}, r-base-core (>= 2.12.2)
Suggests: r-cran-runit, r-cran-fbasics
Description: GNU R package for stable distribution functions
This package provides density, probability and quantile functions,
and random number generation for (skew) stable distributions, using
the parametrizations of Nolan.

and my copyright draft (yes, with an outdated FSF address but I just emailed
Martin about it) is below. There are only three source files and the two
main ones carry the (old) FSF snippets but no per-file copyright assignments.

Cheers, Dirk


This is the Debian GNU/Linux r-cran-stabledist package of stabledist,
a set of function for density, probability and quantile functions, and
random number generation for (skew) stable distributions. It was
factored out of the Rmetrics package fBasics which now depends on
it. Rmetrics is a collection of packages for financial engineering and
computational finance. stabledist was started by Diethelm Wuertz
andwas extended by Martin Maechler who now maintains it.

This package was created by Dirk Eddelbuettel <edd@debian.org>.
The sources were downloaded from the main CRAN site
http://cran.r-project.org/src/contrib/
and are also available from all CRAN mirrors as e.g.
http://cran.us.r-project.org/src/contrib/

The package was renamed from its upstream name 'stabledist' to
'r-cran-stabledist' to fit the pattern of CRAN (and non-CRAN) packages for
R.
