Benjamin Erichson ", "Description": "Sparse principal component analysis (SPCA) attempts to\nfind sparse weight vectors (loadings), i.e., a weight vector\nwith only a few 'active' (nonzero) values. This approach\nprovides better interpretability for the principal components\nin high-dimensional data settings. This is, because the\nprincipal components are formed as a linear combination of only\na few of the original variables. This package provides\nefficient routines to compute SPCA. Specifically, a variable\nprojection solver is used to compute the sparse solution. In\naddition, a fast randomized accelerated SPCA routine and a\nrobust SPCA routine is provided. Robust SPCA allows to capture\ngrossly corrupted entries in the data.", "License": "GPL (>= 3)", "Encoding": "UTF-8", "URL": "https://github.com/erichson/spca", "BugReports": "https://github.com/erichson/spca/issues", "RoxygenNote": "6.0.1", "Repository": "https://erichson.r-universe.dev", "Date/Publication": "2018-04-07 20:15:00 UTC", "RemoteUrl": "https://github.com/erichson/spca", "RemoteRef": "HEAD", "RemoteSha": "fa896289a68801a4798f53948ff6c2b8f7c54e1c", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-22 18:50:36 UTC", "User": "root" }, "MD5sum": "fa39d63777e3614616c00c35dd759a71", "_user": "erichson", "_type": "src", "_file": "sparsepca_0.1.0.tar.gz", "_fileid": "e3a45c2538b9782ae5dc894f8e0b732487254bd57bc1a10ed036b5b05cd4bc92", "_filesize": 700881, "_sha256": "e3a45c2538b9782ae5dc894f8e0b732487254bd57bc1a10ed036b5b05cd4bc92", "_created": "2026-05-22T18:50:36.000Z", "_published": "2026-05-22T19:02:37.984Z", "_distro": "noble", "_jobs": [ { "job": 77443076668, "time": 118, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "NOTE", "artifact": "7168126833" }, { "job": 77443076685, "time": 104, "config": "linux-release-x86_64", "r": "4.6.0", "check": "NOTE", "artifact": "7168123350" }, { "job": 77443076659, "time": 96, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "NOTE", "artifact": "7168178725" }, { "job": 77443076687, "time": 79, "config": "macos-release-arm64", "r": "4.6.0", "check": "NOTE", "artifact": "7168174160" }, { "job": 77442726382, "time": 133, "config": "source", "r": "4.6.0", "check": "OK", "artifact": "7168046493" }, { "job": 77443076665, "time": 94, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "7168120592" }, { "job": 77443076644, "time": 90, "config": "windows-devel", "r": "4.7.0", "check": "NOTE", "artifact": "7168117637" }, { "job": 77443076645, "time": 76, "config": "windows-oldrel", "r": "4.5.3", "check": "NOTE", "artifact": "7168106934" }, { "job": 77443076671, "time": 90, "config": "windows-release", "r": "4.6.0", "check": "NOTE", "artifact": "7168122413" } ], "_buildurl": "https://github.com/r-universe/erichson/actions/runs/26274002788", "_status": "success", "_host": "GitHub-Actions", "_upstream": "https://github.com/erichson/spca", "_commit": { "id": "fa896289a68801a4798f53948ff6c2b8f7c54e1c", "author": "Ben Erichson ", "committer": "Ben Erichson ", "message": "references\n", "time": 1523132100 }, "_maintainer": { "name": "N.
