## About

[Method](/about/licenses.md)

Data recorded as paths or trajectories may be suitably described by curves, which are independent of their parametrization.

**Full description**

Data recorded as paths or trajectories may be suitably described by curves, which are independent of their parametrization. For the space of such curves, the package provides functionalities for reading curves, sampling points on curves, calculating distance between curves and for computing Tukey curve depth of a curve w.r.t. to a bundle of curves. For details see Lafaye De Micheaux, Mozharovskyi, and Vimond (2021) <doi:10.48550/arXiv.1901.00180>.

## Downloads

[Method](/about/downloads.md)

- Downloads in the last 30 days: 297 (down 22.5% on the 30 days before, the worse direction. It is the sum of 3 channels: CRAN, r2u and autoCRAN.)

CRAN alone: rank among CRAN packages, last 30 days: 14,504 of 26,530.

| Channel | Downloads in the last 30 days | In the total | Rank in that channel | Change |
| --- | ---: | --- | --- | --- |
| CRAN | 289 | yes | 14,504 of 26,530 | down 17.4% on the 30 days before, the worse direction |
| r2u | 2 | yes | 14,902 of 30,526 | down 88.2% on the 30 days before, the worse direction |
| autoCRAN | 6 | yes | 8,234 of 29,212 | down 62.5% on the 30 days before, the worse direction |

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

To leave channels out of the total, name them in the address, joined by dots: `?off=r2u.autocran`.

#### Over time

Downloads over time, the last 12 whole months:

| Month | CRAN | r2u | autoCRAN | Sum |
| --- | ---: | ---: | ---: | ---: |
| Oct 2025 | 270 | 43 | no figure | 313 |
| Nov 2025 | 162 | 34 | no figure | 196 |
| Dec 2025 | 141 | 33 | no figure | 174 |
| Jan 2026 | 209 | 29 | no figure | 238 |
| Feb 2026 | 211 | 37 | no figure | 248 |
| Mar 2026 | 255 | 31 | no figure | 286 |
| Apr 2026 | 217 | 48 | no figure | 265 |
| May 2026 | 175 | 45 | no figure | 220 |
| Jun 2026 | 277 | 26 | no figure | 303 |
| Jul 2026 | 253 | 20 | no figure | 273 |
| Aug 2026 | 214 | 19 | 28 | 261 |
| Sep 2026 | 346 | no figure | 15 | not whole yet |

The sum stops at Aug 2026: r2u has no later month on record yet.

First day on record: CRAN 8 Jan 2019, r2u 22 May 2022, autoCRAN 2 Jul 2026.

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.
