Quantlet: tableN
Description: tableN returns a N way table for N-dimensional data.

Usage: {xr,r} = tableN(x)
Input:
x n x N matrix, the columns correspond to the variables.
Output:
xr m x N matrix, includes all possible combinations of values, sorted by last column.
r m x 1 vector, contains the number of replications of each combination. Some values may be 0. The sum of r is equal the count of observations.

Example:

library("stats")

x=(1:4|3)~matrix(5)~(2|2|3|3|3)

{xr,r}=tableN(x)

xr~r

Result:
