{"package":"r-rspectra","ecosystem":"conda","latest_version":"0.16_2","description":"R interface to the 'Spectra' library <http://yixuan.cos.name/spectra/> for large scale eigenvalue and SVD problems. It is typically used to compute a few eigenvalues/vectors of an n by n matrix, e.g., the k largest eigenvalues, which is usually more efficient than eigen() if k << n. This package provides the 'eigs()' function which does the similar job as in 'Matlab', 'Octave', 'Python SciPy' and 'Julia'. It also provides the 'svds()' function to calculate the largest k singular values and corresponding singular vectors of a real matrix. Matrices can be given in either dense or sparse form.","license":"MPL-2.0","license_risk":"weak_copyleft","commercial_use_notes":"MPL-2.0: only modified MPL files must be released; commercial closed-source around it is fine.","homepage":"https://github.com/yixuan/RSpectra","repository":"","downloads_weekly":2122,"health":{"score":52,"risk":"high","breakdown":{"maintenance":10,"popularity":6,"security":25,"maturity":9,"community":2},"deprecated":false,"max_score":100},"vulnerabilities":{"count":0,"critical":0,"high":0,"medium":0,"low":0,"details":[]},"versions":{"latest":"0.16_2","total_count":6,"recent":["0.12_0","0.14_0","0.15_0","0.16_0","0.16_1","0.16_2"]},"metadata":{"deprecated":false,"deprecated_message":null,"maintainers_count":1,"first_published":"2021-05-24 03:31:34.189000+00:00","last_published":"2025-09-10 11:26:14.447000+00:00","dependencies_count":0,"dependencies":[]},"github_stats":null,"bundle":null,"typescript":null,"known_issues":{"bugs_count":0,"bugs_severity":{},"status_breakdown":{},"link":null,"scope":"none"},"historical_compromise":null,"recommendation":{"action":"use_with_caution","issues":["Moderate health score (52/100) — verify manually"],"use_version":"0.16_2","version_hint":null,"summary":"r-rspectra@0.16_2 low health (52/100) — consider alternatives"},"version_scoped":null,"requested_version":null,"_cache":"miss","_response_ms":721,"_powered_by":"depscope.dev — free package intelligence for AI agents","typosquat":{"is_suspected":false},"maintainer_trust":{"available":false},"malicious":{"is_malicious":false},"scorecard":{"available":false},"quality":{"available":false},"version_history_summary":{"total_versions":6,"first_release_age_days":1804,"last_release_days_ago":234,"avg_days_between_releases":361,"release_velocity":"moderate"}}
