Unlike traditional detrending\napproaches that can distort long term growth trends, ABD\ndecomposes ring width series into multiple age classes,\ndetrends each class separately, and then recombines them to\ncreate standardized chronologies. This approach improves the\ndetection of growth signals linked to past climatic and\nenvironmental factors, making it particularly valuable for\ndendroecological and dendroclimatological studies. The package\nprovides functions to perform ABD-based standardization,\ncompare results with other common methods (e.g., BAI, C method,\nRCS), and facilitate the interpretation of growth patterns\nunder current and future climate variability.", "URL": "https://gitlab.com/Puletti/agebanddecomposition_rpackage", "Language": "en-US", "License": "GPL (>= 3)", "Encoding": "UTF-8", "RoxygenNote": "7.3.2", "LazyData": "true", "Config/testthat/edition": "3", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-10 09:19:33 UTC", "User": "root" }, "Author": "Nicola Puletti [aut, cre] (ORCID:\n), Gianluigi Mazza [aut]\n(ORCID: ), Dimitrios\nSarris [ctb] (ORCID: )", "Maintainer": "Nicola Puletti ", "Repository": "https://cran.r-universe.dev", "Date/Publication": "2026-04-10 19:15:24 UTC", "RemoteUrl": "https://github.com/cran/AgeBandDecomposition", "RemoteRef": "HEAD", "RemoteSha": "ace44d762c40b7dbb6bddfbc103b9d4f48e236d1", "MD5sum": "1e4b236ebe660c7e4779a38b8cf2d114", "_user": "cran", "_type": "src", "_file": "AgeBandDecomposition_2.0.1.tar.gz", "_fileid": "7213363b9a87e32a9e7d1ae8d81195544aa097c05ecd03d3561569ac009b1aa4", "_filesize": 2539820, "_sha256": "7213363b9a87e32a9e7d1ae8d81195544aa097c05ecd03d3561569ac009b1aa4", "_created": "2026-05-10T09:19:33.000Z", "_published": "2026-05-22T12:13:10.214Z", "_distro": "noble", "_jobs": [ { "job": 77376977802, "time": 174, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "6902623757" }, { "job": 77376977923, "time": 177, "config": "linux-release-x86_64", "r": "4.6.0", "check": "OK", "artifact": "6902624146" }, { "job": 77376976598, "time": 176, "config": "source", "r": "4.6.0", "check": "OK", "artifact": "6902607347" }, { "job": 77376977029, "time": 121, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "7160183455" } ], "_buildurl": "https://github.com/r-universe/cran/actions/runs/25624979430", "_status": "success", "_host": "GitHub-Actions", "_upstream": "https://github.com/cran/AgeBandDecomposition", "_commit": { "id": "ace44d762c40b7dbb6bddfbc103b9d4f48e236d1", "author": "Nicola Puletti ", "committer": "cran-robot ", "message": "version 2.0.1\n", "time": 1775848524 }, "_maintainer": { "name": "Nicola Puletti", "email": "nicola.puletti@crea.gov.it", "orcid": "0000-0002-2142-959X" }, "_registered": true, "_dependencies": [ { "package": "R", "version": ">= 4.1.0", "role": "Depends" }, { "package": "dplyr", "role": "Imports" }, { "package": "tidyr", "role": "Imports" }, { "package": "tibble", "role": "Imports" }, { "package": "readxl", "role": "Imports" }, { "package": "ggplot2", "role": "Imports" }, { "package": "dplR", "role": "Imports" }, { "package": "patchwork", "role": "Imports" }, { "package": "testthat", "version": ">= 3.0.0", "role": "Suggests" } ], "_owner": "cran", "_selfowned": false, "_usedby": 0, "_updates": [ { "week": "2025-31", "n": 1 }, { "week": "2026-06", "n": 1 }, { "week": "2026-15", "n": 1 } ], "_tags": [ { "name": "1.0.1", "date": "2025-07-28" }, { "name": "2.0.0", "date": "2026-02-04" }, { "name": "2.0.1", "date": "2026-04-10" } ], "_stars": 0, "_userbio": { "uuid": 6899542, "type": "organization", "name": "cran", "description": "Unofficial read-only mirror of all CRAN R packages" }, "_downloads": { "count": 561, "source": "https://cranlogs.r-pkg.org/downloads/total/last-month/AgeBandDecomposition" }, "_devurl": "https://gitlab.com/puletti/agebanddecomposition_rpackage", "_searchresults": 0, "_rbuild": "4.6.0", "_assets": [ "extra/AgeBandDecomposition.html", "extra/citation.cff", "extra/citation.html", "extra/citation.json", "extra/citation.txt", "extra/contents.json", "extra/NEWS.html", "extra/NEWS.txt", "extra/readme.html", "extra/readme.md", "manual.pdf" ], "_homeurl": "https://gitlab.com/puletti/agebanddecomposition_rpackage", "_realowner": "cran", "_cranurl": false, "_releases": [ { "version": "1.0.1", "date": "2025-08-01" }, { "version": "2.0.0", "date": "2026-02-04" }, { "version": "2.0.1", "date": "2026-04-10" } ], "_exports": [ "ABD", "import_rwl", "plotABD", "plotBAI", "plotTRW", "stdTRW", "TRW_readExcel" ], "_datasets": [ { "name": "inTRW", "title": "AgeBandDecomposition test data", "object": "inTRW", "class": [ "list" ], "fields": [], "table": false, "tojson": true }, { "name": "po_test_data", "title": "AgeBandDecomposition: pith-offset test data", "object": "po_test_data", "class": [ "data.frame" ], "fields": [ "tree", "pith.offset" ], "rows": 21, "table": true, "tojson": true }, { "name": "rwl_test_data", "title": "AgeBandDecomposition: rwl test data", "object": "rwl_test_data", "class": [ "rwl", "data.frame" ], "fields": [ "tree01", "tree02", "tree03", "tree04", "tree05", "tree06", "tree07", "tree08", "tree09", "tree10", "tree11", "tree12", "tree13", "tree14", "tree15", "tree16", "tree17", "tree18", "tree19", "tree20", "tree21" ], "rows": 189, "table": true, "tojson": true } ], "_help": [ { "page": "ABD", "title": "ABD -
