Hello again,

I was hoping one of you could help me with this problem. Consider the sample data from R:

> summary(prcomp(USArrests))
Importance of components:
                          PC1     PC2    PC3     PC4
Standard deviation     83.732 14.2124 6.4894 2.48279
Proportion of Variance  0.966  0.0278 0.0058 0.00085
Cumulative Proportion   0.966  0.9933 0.9991 1.00000

How do I access the information contained within this summary? For instance, let's say I wanted to make a graph based on the second row ("Proportion of Variance"). 

Please rest assured this is not a homework assignment. I'm just a relatively novice R user trying to do stuff that's often over my head.

Thanks in advance,
