For a large number of bars, sometimes this:

 plot( y, type='h') # maybe use lwd=5

>> I have a vector like say 73,53,42,67,41,50 where these numbers are the number of occurrences of the data values 1,2,3,4,5,6 - so in essence I have the frequency bit from the hist() function.  I can't see an elegant way (there are clearly messy workarounds like generating a vector of 73 1's, 53 2's etc) of creating a histogram from this data set.  Is there one?
