Hi, Please look at the distribution task view (http://cran.r-project.org/web/views/Distributions.html) and the package gamlss.dist.
By the way, distributions in R are implemented in <source>/src/nmath directory and not <source>/src/library/stats Regards Christophe -- Christophe Dutang Ph.D. student at ISFA, Lyon, France website: http://dutangc.free.fr Le 16 mars 2012 à 18:41, Joan Maspons a écrit : > Hi, > I need Beta binomial and Beta negative binomial functions but in R there is > only SuppDists package which provide this distributions using a limited > parameter space of the generalized hypergeometric distribution (dghyper & Co.) > which provide a limited parameter space for Beta binomial and Beta negative > binomial functions (e.g. alpha + beta <1 in the Beta negative binomial). > > I've done a checkout to R svn to seek the code for the implementation of > distribution functions (dbinom et al.) but I haven't succeed.
