如下通过R进行因子分析后,我得到了结果。

PCAVar <- principal(Corr, nfactors=7, rotate="varimax")

以下是我可以获得的所有对象:

names(PCAVar)

[1] "values"       "rotation"     "n.obs"        "communality"  "loadings"     "fit"          "fit.off"     
[8] "fn"           "Call"         "uniquenesses" "complexity"   "chi"          "EPVAL"        "R2"          
[15] "objective"    "residual"     "rms"          "factors"      "dof"          "null.dof"     "null.model"  
[22] "criteria"     "PVAL"         "weights"      "r.scores"     "rot.mat"      "Structure"

我想在分类中使用这些因素。但是,我不知道如何将因子加载到我的训练数据集中。
