[R] printing levels as tuples

[Alexy Khrabrov]

I'm running rle() on a long vector, and get a result which looks like

 > uc
Run Length Encoding
   lengths: int [1:16753] 1 1 1 1 1 1 1 1 1 1 ...
   values : int [1:16753] 29462748 22596107 18322820 14323315  
12684505 9909036 7296916 6857692 5884755 5883697 ...


I can print uc$names or uc$levels separately.  Is there any way to  
print them together as tuples, looking like

(29462748, 1)   (22596107, 1) ...
(5883697, 1) ...
...

Cheers,
Alexy
