我正在对数据状态进行因子分析。x77,默认在R中。在运行分析之后,我检查了因子加载。
> output = factanal(state.x77, factors=3, rotation="promax")
> ld = output$loadings
> ld
Loadings:
Factor1 Factor2 Factor3
Population 0.161 0.239 -0.316
Income -0.149 0.681
Illiteracy 0.446 -0.284 -0.393
Life Exp -0.924 0.172 -0.221
Murder 0.917 0.103 -0.129
HS Grad -0.414 0.731
Frost 0.107 1.046
Area 0.387 0.585 0.101
Factor1 Factor2 Factor3
SS loadings 2.274 1.519 1.424
Proportion Var 0.284 0.190 0.178
Cumulative Var 0.284 0.474 0.652
看起来默认情况下R阻塞所有小于0.1的值。我想知道是否有一种方法可以手动设置这个阻塞级别,比如0.3而不是0.1?
try this:
print(output$loadings, cutoff = 0.3)
详情见?print.loadings
