| Description: | computes a two way table from two-dimensional data. |
| Usage: | {x1,x2,t}=table2(x) | |
| Input: | ||
| x | n x 2 matrix, the columns correspond to the variables. | |
| Output: | ||
| x1 | p x 1 vector, distinct realizations of x[,1]. | |
| x2 | q x 1 vector, distinct realizations of x[,2]. | |
| t | p x q matrix, the absolute frequencies (the inner part of the crosstable). | |
