Hi, I've reorganized my data using crosstab to obtain the orientation below. There are categories, the users for those categories and the amount of times they've used the category.
| Category | U1 | U2 | U3 |
| A | 1 | 3 | 0 |
| B | 0 | 1 | 0 |
| C | 3 | 0 | 2 |
I would like to do something to the above data to obtain the following table:
| Category | Users |
| A | U2, U1 |
| B | U2 |
| C | U1, U3 |
Notice they are in order of who has the most user (this is not absolutely necessary if too difficult)
Thanks in advance for the help.
