## Downloads

[Method](/about/downloads.md)

- Downloads in the last 30 days: 322 (down 15.3% on the 30 days before, the worse direction. It is the sum of 4 channels: CRAN, r2u, autoCRAN and c2d4u.)

CRAN alone: rank among CRAN packages, last 30 days: 12,419 of 26,530.

| Channel | Downloads in the last 30 days | In the total | Rank in that channel | Change |
| --- | ---: | --- | --- | --- |
| CRAN | 318 | yes | 12,419 of 26,530 | down 11.9% on the 30 days before, the worse direction |
| r2u | 2 | yes | 14,902 of 30,526 | down 66.7% on the 30 days before, the worse direction |
| autoCRAN | 1 | yes | 25,688 of 29,212 | down 80% on the 30 days before, the worse direction |
| c2d4u | 1 | yes | 5,617 of 7,575 | down 87.5% on the 30 days before, the worse direction |

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

To leave channels out of the total, name them in the address, joined by dots: `?off=autocran.c2d4u`.

First day on record: CRAN 6 Oct 2012, r2u 22 May 2022, autoCRAN 1 Jul 2026, c2d4u 14 Jun 2020 (no longer updated).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.

Graph: the whole call graph has 2 function names that take part in a call and 1 call between them, set out in 2 layers with callers before what they call. Called by the most functions: `separationplot` (1), `sp.categorical` (0). Calling the most functions: `sp.categorical` (1), `separationplot` (0).

Most connected functions: [`separationplot`](/cran/separationplot.md?fn=separationplot&view=focus#code) 1, [`sp.categorical`](/cran/separationplot.md?fn=sp.categorical&view=focus#code) 1
