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 . 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.
