Standard aggregation in the lambda framework\nmaintains consistent lambda and stable stage distribution,\nwhile standard aggregation in the R0 framework maintains\nconsistent R0 and cohort stable stage distribution.\nElasticity-consistent aggregators maintain these same\nconsistencies with respect to the chosen framework and\nadditionally preserve consistent reproductive values in the\nlambda framework and cohort reproductive values in the R0\nframework. Aggregation can take the form of general-to-general\nMPM (mpm_aggregate) or Leslie-to-Leslie MPM (leslie_aggregate).", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "Config/testthat/edition": "3", "VignetteBuilder": "knitr", "LazyData": "true", "Config/roxygen2/version": "8.0.0", "Repository": "https://hinrich62.r-universe.dev", "Date/Publication": "2026-05-24 01:47:48 UTC", "RemoteUrl": "https://github.com/hinrich62/mpmaggregate", "RemoteRef": "HEAD", "RemoteSha": "04661045b125c53f473f28d7eca97c717f5f616e", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-24 02:57:57 UTC", "User": "root" }, "MD5sum": "9fdb3ef326669c0544b2045365d4edec", "_user": "hinrich62", "_type": "src", "_file": "mpmaggregate_0.2.6.tar.gz", "_fileid": "9e36ef1e195373a466fc36e8dc55fde0b1ebd276cb60a3d6b3886bbe981d7b15", "_filesize": 1376491, "_sha256": "9e36ef1e195373a466fc36e8dc55fde0b1ebd276cb60a3d6b3886bbe981d7b15", "_created": "2026-05-24T02:57:57.000Z", "_published": "2026-05-24T03:01:12.779Z", "_distro": "noble", "_jobs": [ { "job": 77566999540, "time": 129, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "7181709584" }, { "job": 77566999531, "time": 161, "config": "linux-release-x86_64", "r": "4.6.0", "check": "OK", "artifact": "7181712751" }, { "job": 77566999533, "time": 121, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "7181707522" }, { "job": 77566999538, "time": 139, "config": "macos-release-arm64", "r": "4.6.0", "check": "OK", "artifact": "7181708033" }, { "job": 77566832700, "time": 218, "config": "source", "r": "4.6.0", "check": "OK", "artifact": "7181698469" }, { "job": 77566999534, "time": 121, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "7181708889" }, { "job": 77566999539, "time": 85, "config": "windows-devel", "r": "4.7.0", "check": "OK", "artifact": "7181705918" }, { "job": 77566999556, "time": 73, "config": "windows-oldrel", "r": "4.5.3", "check": "OK", "artifact": "7181704783" }, { "job": 77566999541, "time": 74, "config": "windows-release", "r": "4.6.0", "check": "OK", "artifact": "7181704963" } ], "_buildurl": "https://github.com/r-universe/hinrich62/actions/runs/26350161013", "_status": "success", "_host": "GitHub-Actions", "_upstream": "https://github.com/hinrich62/mpmaggregate", "_commit": { "id": "04661045b125c53f473f28d7eca97c717f5f616e", "author": "Richard Hinrichsen ", "committer": "Richard Hinrichsen ", "message": "Prepare release 0.2.6\n", "time": 1779587268 }, "_maintainer": { "name": "Richard A.
