[R] Libraries loading, but not really?

[kalish@psy.uwa.edu.au]

I'm a newbie at R, and can't get libraries to really work.
I did this:
> library(help = mva)
cancor                   Canonical Correlations
cmdscale                 Classical (Metric) Multidimensional Scaling
dist                     Distance Matrix Computation
hclust                   Hierarchical Clustering
kmeans                   K-Means Clustering
prcomp                   Principal Components Analysis
> (pc.cr<-princomp(USArrests))
Error: couldn't find function "princomp"
> 

I should say that ?princomp works beautifully, but the function itself
is absent.  
I imagine I have done something stupid in installation?

thanks,
