[R] princomp() output loadings component missing

[Fix Ace]

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.
Ace
