It does help, Dan!  I came up with the same idea and expanded on it a bit 
to work properly with other kinds of vectors:

as.vector(table( as.character(vec) )[as.character(vec)])

If there are, say, 10,000 different elements in vec, each repeated an 
average of 5-10 times, will this still work correctly?  In other words, 
the length of the table output array is unlimited, right?
