[R] Problem with tensor factorization

[Peppe Ricci]

Hi,

thank Petr for your help.
I have implemented you code suggestion but there is another problem.
It seems that the code:

for (i in 1:m){
 Z[i,,]=table(occ, data_matrix[,i])
}

don't charge any values in Z.
Is there some error?
Thanks.
Giuseppe
