 Usage:  cross=crosstable(x{,xvars})  

 

 Input:



  x                      n x p matrix, the columns correspond to the variables. 

                         

  xvars                  optional, p x 1 string vector, variable names. 

                         

 Output:



  cross                  string output, containing all crosstables of each 

                         combinations of columns of x, the result of the 

                         Chi-square independence tests and contingency 

                         coefficients.
