Subject: princomp() output loadings component missing
In-Reply-To: <825389587.741141.1481055296512@mail.yahoo.com>
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.
