R help - Oct 2007 - Variable characterization by the modalities of other variables

Dear Sirs,

Is there a way to make  in R a variable modalities characterisation by 
the modalities of other categorical variables?

Usually I do this task in SPAD. The output are:

column 3 --  modality %  in the class
column 4 -- modality  % in the population
column 5 -- class % in the modality

suppose:
                 Variable A (two modalities: A1 and A2) dependent 
variable
                 Variable B (two modalities: B1 and B2) independent 
variable

variable A - modality A1

Variable---------Modality-------- column 3-------- column 4 ---- column 
5 ---- chi-squared ---- p-value
A                               A1                         100          
        67.45             40.87                2                         
0,00
B                               B2                         56           
         23                    45                     1.8                
       0,00


variable A -- modality A2

Variable---------Modality-------- column 3-------- column 4 ---- column 
5 ---- chi-squared ---- p-value
A                               A2                         100          
        57.45             30.28                3                         
0,00
B                               B1                         38           
         32                    25                     2.3

Have a nice night
Thanks a lot
