I have a dataframe with 100k rows and 20 binary variables, one of which is my target.

I would like to apply a Correspondence Analysis (CA) on it, but I have a few doubts:

 1. should the target column be included into the CA?

 2. CA is a way to analyze a large contingency table.   The command `table` is used to get the contingency table but I get as many 2x2 tables as there are pairwise combinations of variables. Instead, correct me if I'm wrong, I need just one table with the counts for each column relative to my target variable, like:
     ```
             var1    var2   ...  var19 
    target
    
       0      73k     45k   ...   60k

       1      37k     55k   ...   40k
      ```

     Is there an R function that does this?
