This package incorporates three\nmodular Shiny apps to implement a human-in-the-loop framework.\n(1) a manual extraction interface for abstracts, (2) refining\nprompt engineering and model selection, and (3) validation of\nLLM-generated outputs. These apps enable researchers to\niteratively collaborate with LLMs, with each abstract\nundergoing double data extraction—once manually by a human\nresearcher and once independently by an LLM-assisted process—to\nemulate the double extraction process recommended by\ninternational standards. Notably, the package runs fully on\nlocal machines, with no need for API setup or external data\ntransfer, maximising data privacy and accessibility. Robust\nlogging features further enhance transparency and\nreproducibility by recording all prompt iterations and outputs.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "7.3.2", "Config/testthat/edition": "3", "URL": "https://danyangdai.github.io/metaextractoR/", "BugReports": "https://github.com/DanyangDai/metaextractoR/issues", "Config/pak/sysreqs": "cmake make libicu-dev libuv1-dev libssl-dev\nzlib1g-dev", "Repository": "https://emitanaka.r-universe.dev", "Date/Publication": "2026-04-07 22:22:39 UTC", "RemoteUrl": "https://github.com/DanyangDai/metaextractoR", "RemoteRef": "HEAD", "RemoteSha": "229c8547ffc83f73d418a860254f066023d9ec0d", "NeedsCompilation": "no", "Packaged": { "Date": "2026-07-05 08:34:35 UTC", "User": "root" }, "Author": "Danyang Dai [aut, cre, cph] (ORCID:\n),\nEmi Tanaka [aut] (ORCID: ),\nJason Pole [ths] (ORCID: )", "Maintainer": "Danyang Dai ", "_user": "emitanaka", "_type": "src", "_file": "metaextractoR_0.1.0.tar.gz", "_fileid": "https://r2.ropensci.org/abda8d935b1bb6a6878dc8fdaba39b051fccb8bf87329fbba15ae385e4c2bac9", "_filesize": 234632, "_sha256": "abda8d935b1bb6a6878dc8fdaba39b051fccb8bf87329fbba15ae385e4c2bac9", "_expires": "2026-10-13T08:37:37.000Z", "_created": "2026-07-05T08:34:35.000Z", "_published": "2026-07-05T08:37:38.530Z", "_jobs": [ { "job": 85207312736, "time": 138, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "8090039163" }, { "job": 85207312715, "time": 144, "config": "linux-release-x86_64", "r": "4.6.1", "check": "OK", "artifact": "8090039783" }, { "job": 85207312720, "time": 79, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "8090031888" }, { "job": 85207312721, "time": 100, "config": "macos-release-arm64", "r": "4.6.1", "check": "OK", "artifact": "8090034533" }, { "job": 85207094977, "time": 204, "config": "source", "r": "4.6.1", "check": "OK", "artifact": "8090021911" }, { "job": 85207312702, "time": 149, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "8090040454" }, { "job": 85207312705, "time": 79, "config": "windows-devel", "r": "4.7.0", "check": "OK", "artifact": "8090031838" }, { "job": 85207312710, "time": 91, "config": "windows-oldrel", "r": "4.5.3", "check": "OK", "artifact": "8090033859" }, { "job": 85207312706, "time": 93, "config": "windows-release", "r": "4.6.1", "check": "OK", "artifact": "8090033941" } ], "_host": "GitHub-Actions", "_buildurl": "https://github.com/r-universe/emitanaka/actions/runs/28734853027", "_status": "success", "_upstream": "https://github.com/DanyangDai/metaextractoR", "_commit": { "id": "229c8547ffc83f73d418a860254f066023d9ec0d", "author": "danyangdai <43340871+DanyangDai@users.noreply.github.com>", "committer": "danyangdai <43340871+DanyangDai@users.noreply.github.com>", "message": "Ellmer removed extract_data and replace with chat$chat_structured(...)\n", "time": 1775600559 }, "_maintainer": { "name": "Danyang Dai", "email": "danyan.dai01@gmail.com", "login": "danyangdai", "uuid": 43340871 }, "_distro": "resolute", "_registered": true, "_dependencies": [ { "package": "R", "version": ">= 3.5", "role": "Depends" }, { "package": "ellmer", "role": "Imports" }, { "package": "shiny", "role": "Imports" }, { "package": "tidyr", "role": "Imports" }, { "package": "shinyFiles", "role": "Imports" }, { "package": "cli", "role": "Imports" }, { "package": "dplyr", "role": "Imports" }, { "package": "fs", "role": "Imports" }, { "package": "methods", "role": "Imports" }, { "package": "DT", "role": "Imports" }, { "package": "bslib", "role": "Imports" }, { "package": "shinyjs", "role": "Imports" }, { "package": "testthat", "version": ">= 3.0.0", "role": "Suggests" } ], "_owner": "danyangdai", "_selfowned": false, "_usedby": 0, "_updates": [ { "week": "2025-29", "n": 1 }, { "week": "2025-34", "n": 3 }, { "week": "2025-36", "n": 3 }, { "week": "2025-41", "n": 1 }, { "week": "2025-42", "n": 10 }, { "week": "2025-43", "n": 49 }, { "week": "2025-44", "n": 27 }, { "week": "2026-15", "n": 1 } ], "_tags": [], "_stars": 4, "_contributors": [ { "user": "emitanaka", "count": 69, "uuid": 7620319 }, { "user": "danyangdai", "count": 56, "uuid": 43340871 } ], "_userbio": { "uuid": 7620319, "type": "user", "name": "Emi Tanaka", "followers": 544, "description": "Senior Lecturer in Statistics.
