I do not see an error in this part of the code, but there
may be an error in the context, in which this code is used.

Did you look at the value of table(occ, data_matrix[,i])
at the time, when the command is executed?

If the command 

  Z[i,,]=table(occ, data_matrix[,i])

does not stop with an error, then it does not change Z[i,,] if
Z[i,,] contains the values equal to table(occ, data_matrix[,i])
already before the command is executed. This may happen, for 
example, if you run the command twice.
