- conda-forge: `conda install -c conda-forge r-teachingdemos` _Listed from recorded download activity on this channel, not from a live index, so read it as last known._

- CRAN checks: OK (notes on 5 of 13)
- CRAN 30-day downloads: 24,412 (up 139% on the 30 days before, the better direction)

## Downloads

[Method](/about/downloads.md)

- Downloads in the last 30 days: 26,185 (up 127% on the 30 days before, the better direction. It is the sum of 5 channels: CRAN, r2u, autoCRAN, conda-forge and c2d4u.)

CRAN alone: rank among CRAN packages, last 30 days: 720 of 26,530.

| Channel | Downloads in the last 30 days | In the total | Rank in that channel | Change |
| --- | ---: | --- | --- | --- |
| CRAN | 24,412 | yes | 720 of 26,530 | up 139% on the 30 days before, the better direction |
| r2u | 906 | yes | 865 of 30,526 | up 1,385% on the 30 days before, the better direction |
| autoCRAN | 222 | yes | 152 of 29,212 | down 21.8% on the 30 days before, the worse direction |
| conda-forge | 640 | yes | 1,306 of 3,828 | down 31% on the 30 days before, the worse direction |
| c2d4u | 5 | yes | 3,123 of 7,575 | down 77.3% on the 30 days before, the worse direction |

First day on record: CRAN 5 Oct 2012, r2u 8 May 2022, autoCRAN 29 Jun 2026, conda-forge 26 Dec 2018, c2d4u 20 Jul 2011 (no longer updated).

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.
