[R] Sampling given a table of percentages?

[Ben Hyde]

I have a vector V.  sum(V) = 100, i.e. it's percentages.  length(V) is 
large.  I wish to generate samples (with replacement is fine), 
integers, in the range 1:length(V) who's distribution is driven by the 
distribution implied by the percentages in V.    V is unsorted, but 
that could change.  I'd rather not be too specific about the 
distribution of V.    I can certainly solve the problem intersecting my 
thin knowledge of R with my skills in programming, but I suspect this 
is trivial to somebody fluent in R.   Suggestions?  Thanks!  - ben
