library(help= <anypackage>)   
	   doesn't actually list ALL functions in package <anypackage>.
It only lists the supposedly important ones 
	   (that the package maintainers have put in the INDEX file).
However, you are right, "princomp" should be on that list (same as biplot),
and it will be in the next version.

If you look at the output of
   library(help = mva)
the last of only six lines is 
    prcomp   Principal Components Analysis
and from
you see that there's both  prcomp() and princomp()...

In short
