relationship between two factors

I have a dataset with two variables that are factors:

1) Decision Making Satisfaction (DMS), values = A - Completely, B - 
Mostly, C - Partly, D - Not at all
2) IT Satisfaction values (ITS), values = A - Completely, B - Mostly, C 
- Partly, D - Not at all

I would like to produce a table (matrix) and a chart of the factors, 
with counts at the cross sections:

         A   B   C   D
A   
B       counts
C
D

How can I do this in R?

Many thanks,

Chris
