Probability Distributions as S3 Objects R package distributions3 version 0.2.4 CRAN Task View: Distributions (https://CRAN.R-project.org/view=Distributions) Tools to create and manipulate probability distributions using S3. Generics pdf(), cdf(), quantile(), and random() provide replacements for base R's d/p/q/r style functions. Functions and arguments have been named carefully to minimize confusion for students in intro stats courses. The documentation for each distribution contains detailed mathematical notes.
