Statistical modeling with DataTable

Description:

     A number of wrappers are implemented for performing statistical
     procedures, such as model fitting, with 'DataTable' objects.

Tabulation:


      'xtabs(formula = ~., data, subset, na.action,  exclude = c(NA,
          NaN), drop.unused.levels = FALSE)': Like the original
          'xtabs', except 'data' is a 'DataTable'.


See Also:

     'DataTable' for general manipulation, 'DataFrame' for an
     implementation that mimics 'data.frame'.

Examples:

       df <- DataFrame(as.data.frame(UCBAdmissions))
       xtabs(Freq ~ Gender + Admit, df)
