Hello, there,
I did a test run for this princomp() function using USArrests data. The R
document says that the output loadings contain the eigenvector matrix. When I
looked at this matrix, I found that a missing item for Comp.4
> p3=princomp(USArrests, cor=TRUE )> p3$loadings
Loadings: Comp.1 Comp.2 Comp.3 Comp.4Murder -0.536 0.418 -0.341
0.649Assault -0.583 0.188 -0.268 -0.743UrbanPop -0.278 -0.873 -0.378
0.134Rape -0.543 -0.167 0.818
Comp.1 Comp.2 Comp.3 Comp.4SS loadings 1.00 1.00 1.00
1.00Proportion Var 0.25 0.25 0.25 0.25Cumulative Var 0.25 0.50
0.75 1.00
How should I explain this?
Thanks.
