Hi r-help!

Consider the following data-frame:

   var1 var2 var3 
1     3    1    4 
2     2    2    3 
3     2    2    3 
4     4    4   NA 
5     4    3    5 
6     2    2    3 
7     3    4    3 

How can I get R to convert this into the following?

Value 1  2  3  4  5 
var1  0  3  2  2  0
var2  1  3  1  2  0 
var3  0  0  4  1  1

TIA,
