## About

[Method](/about/licenses.md)

Compose data for and extract, manipulate, and visualize posterior draws from Bayesian models ('JAGS', 'Stan', 'rstanarm', 'brms', 'MCMCglmm', 'coda', ...) in a tidy data format.

**Full description**

Compose data for and extract, manipulate, and visualize posterior draws from Bayesian models ('JAGS', 'Stan', 'rstanarm', 'brms', 'MCMCglmm', 'coda', ...) in a tidy data format. Functions are provided to help extract tidy data frames of draws from Bayesian models and that generate point summaries and intervals in a tidy format. In addition, 'ggplot2' 'geoms' and 'stats' are provided for common visualization primitives like points with multiple uncertainty intervals, eye plots (intervals plus densities), and fit curves with multiple, arbitrary uncertainty bands.

#### Package

Run in R for the authors' preferred citation:

`citation("tidybayes")`

The package provides a citation file that builds its entry when R runs it. Run `citation()` to see it.

## Downloads

[Method](/about/downloads.md)

- Downloads in the last 30 days: 6,736 (up 3.7% on the 30 days before, the better direction. It is the sum of 4 channels: CRAN, r2u, autoCRAN and conda-forge.)

CRAN alone: rank among CRAN packages, last 30 days: 1,548 of 26,530.

| Channel | Downloads in the last 30 days | In the total | Rank in that channel | Change |
| --- | ---: | --- | --- | --- |
| CRAN | 5,240 | yes | 1,548 of 26,530 | down 11% on the 30 days before, the worse direction |
| r2u | 733 | yes | 966 of 30,526 | up 169% on the 30 days before, the better direction |
| autoCRAN | 119 | yes | 564 of 29,212 | up 2.6% on the 30 days before, the better direction |
| conda-forge | 644 | yes | 1,299 of 3,828 | up 194% on the 30 days before, the better direction |

Other windows: [Last 90 days](/cran/tidybayes.md?win=90d#downloads), [Last 365 days](/cran/tidybayes.md?win=365d#downloads), [All time](/cran/tidybayes.md?win=all#downloads).

To leave channels out of the total, name them in the address, joined by dots: `?off=autocran.conda_forge`.

| Sep 2026 | 6,156 | 729 | 108 | 644 | 7,637 |

First day on record: CRAN 2 Aug 2018, r2u 8 May 2022, autoCRAN 29 Jun 2026, conda-forge 1 Oct 2018.

Every channel here counts downloads, so the channels can be stacked and summed for one period. Each channel counts in its own way and covers a different span of years, so read a sum as a rough total, and read a rise where a channel begins as that channel starting, not as growth.

Weeks start on Monday. A first or last week or month that the channel does not cover in full is left out, so every point is a whole period.

Days with no record add nothing to their week or month. For a little-used package that is usually a day with no downloads, but it can also be a gap in collection.
