Yes! That works without any error messages.
Really, I should have checked and found those missing values. It's because some countries are
present in the 2010 wave, but not in 2000 or 2005.
- Code: Select all
country of | Wave
interview | 2000 2005 2010 | Total
------------+---------------------------------+----------
| (Non-missing countries omitted) |
. | 0 0 5,176 | 5,176

Total | 21,703 29,680 43,816 | 95,199
Thanks again for your (speedy) help,
