The functions implement Gradient Projection (GP) algorithms for\northogonal and oblique rotation. Additionally, a number of rotation criteria\nare provided. The GP algorithms minimize the rotation criterion function, and\nprovide the corresponding rotation matrix. For oblique rotation, the\ncovariance/correlation matrix of the factors is also provided.","flavors":[],"html":"https://daemonports.org/dragonfly/math/R-cran-GPArotation/","kind":"port","lastUpdate":null,"license":["GPLv2","GPLv3"],"maintainer":"uzsolt@FreeBSD.org","name":"R-cran-GPArotation","newest":false,"newestVersion":"2026.8.2","noVulnData":false,"origin":"math/R-cran-GPArotation","otherSystems":[{"maintainer":"uzsolt@FreeBSD.org","newest":true,"origin":"math/R-cran-GPArotation","path":"/math/R-cran-GPArotation/","system":"FreeBSD","updated":"2026-10-20","version":"2026.8.2"},{"maintainer":"uzsolt@FreeBSD.org","newest":true,"noVulnData":true,"origin":"math/R-cran-GPArotation","path":"","system":"HardenedBSD","version":"2026.8.2"},{"maintainer":"uzsolt@FreeBSD.org","newest":true,"noVulnData":true,"origin":"math/R-cran-GPArotation","path":"","system":"GhostBSD","version":"2026.8.2"}],"packages":null,"pkgName":"R-cran-GPArotation-2024.3.1","related":null,"repository":"DPorts","requiredBy":["math/R-cran-psych"],"requiredByCount":1,"runDepends":["math/R"],"status":null,"system":"dragonfly","systemLabel":"DragonFly","version":"2024.3.1","versions":null,"vulnerabilities":null,"www":"https://cran.r-project.org/web/packages/GPArotation/index.html"}
