Overview

About

Maintained by Mitchell O'Hara-WildCRAN page ↗GitHub ↗Website ↗Issues ↗

Vectorised distribution objects with tools for manipulating, visualising, and using probability distributions. Designed to allow model prediction outputs to return distributions rather than their parameters, allowing users to directly interact with predictive distributions in a data-oriented workflow. In addition to providing generic replacements for p/d/q/r functions, other useful statistics can be computed including means, variances, intervals, and highest density regions.

Changes in 0.9.0

New features

Added a vignette("broadcasting") to describe how statistics apply to vectors of distributions differently based on the form of the statistical operation's argument (scalar, vector, or list).
Added dist_density(), a distribution characterised by the values of its probability density function at a set of points. This is useful for representing a distribution known only through its density, such as a kernel density estimate or a posterior evaluated over a grid.
Added dist_cdf(), which describes a distribution by the cumulative probabilities at a set of values. Interpolation is done linearly, and the results are equivalent to dist_quantile() with swapped arguments.
Added dist_tweedie(), for the Tweedie compound Poisson-Gamma distribution with power parameter in (1, 2), using the tweedieDistr package (@StefanoDamato).

Show all changes in 0.9.0Hide the rest of the changes in 0.9.0

Added recursive option for parameters(), which recursively extracts the parameters of inner distributions to return a flat data frame (#161).
Added recursive option for family(), which identifies the families of distributions embedded within another (e.g. dist_mixture()) returning a nested list describing the full family tree (#110).

Breaking changes

generate()'s times argument no longer accepts length-n vectors, and instead requires times = list(c(...)) for consistency with other operations.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("distributional", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("mitchelloharawild/distributional")

Development version from mitchelloharawild/distributional. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-distributional

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-distributional

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-distributional

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
