## About

[Method](/about/licenses.md)

Methods to detect genetic markers involved in biological adaptation. 'pcadapt' provides statistical tools for outlier detection based on Principal Component Analysis. Implements the method described in (Luu, 2016) <DOI:10.1111/1755-0998.12592> and later revised in (Privé, 2020) <DOI:10.1093/molbev/msaa053>.

**Cite**

#### Package

Run in R for the authors' entry:

`citation("pcadapt")`

The package provides a citation file, so `citation()` returns the authors' own entry.

It points to 10.1093/molbev/msaa053.

## Downloads

[Method](/about/downloads.md)

- Downloads in the last 30 days: 448 (up 215% on the 30 days before, the better direction. It is the sum of 3 channels: r2u, autoCRAN and conda-forge. CRAN is switched off.)

CRAN alone: rank among CRAN packages, last 30 days: 4,481 of 26,530.

| Channel | Downloads in the last 30 days | In the total | Rank in that channel | Change |
| --- | ---: | --- | --- | --- |
| CRAN | 707 | no, switched off | 4,481 of 26,530 | down 24% on the 30 days before, the worse direction |
| r2u | 94 | yes | 2,393 of 30,526 | up 185% on the 30 days before, the better direction |
| autoCRAN | 4 | yes | 13,992 of 29,212 | down 73.3% on the 30 days before, the worse direction |
| conda-forge | 350 | yes | 1,840 of 3,828 | up 272% on the 30 days before, the better direction |

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

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

#### Over time

Downloads over time, the last 12 whole months:

| Month | r2u | autoCRAN | conda-forge | Sum |
| --- | ---: | ---: | ---: | ---: |
| Oct 2025 | 30 | no figure | 394 | 424 |
| Nov 2025 | 34 | no figure | 378 | 412 |
| Dec 2025 | 31 | no figure | 656 | 687 |
| Jan 2026 | 28 | no figure | 300 | 328 |
| Feb 2026 | 37 | no figure | 202 | 239 |
| Mar 2026 | 52 | no figure | 178 | 230 |
| Apr 2026 | 52 | no figure | 96 | 148 |
| May 2026 | 42 | no figure | 254 | 296 |
| Jun 2026 | 25 | no figure | 159 | 184 |
| Jul 2026 | 52 | 35 | 172 | 259 |
| Aug 2026 | 33 | 30 | 95 | 158 |
| Sep 2026 | 90 | 11 | 350 | 451 |

First day on record: r2u 22 May 2022, autoCRAN 29 Jun 2026, conda-forge 18 Oct 2023.

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.

3 files with no calls to or from another: `R/pcadaptUtils.R`, `R/plotUtils.R`, `src/bed-acc-xptr.cpp`.

The whole package has 78 function names in 18 files and 68 calls between them. Most calls between files: `R/iram.R` and `R/RcppExports.R` (7 calls), `R/RcppExports.R` and `src/RcppExports.cpp` (5 calls), `R/RcppExports.R` and `src/clumping.cpp` (4 calls), `src/bed2matrix.cpp` and `src/vcfUtils.cpp` (3 calls), `R/bed2matrix.R` and `R/RcppExports.R` (2 calls).

Graph: the whole call graph has 64 function names that take part in a call and 68 calls between them, set out in 8 layers with callers before what they call. Of these calls, 2 close a loop and run the other way. 14 function names have no calls and are left out.
