Note that Hadley has since implemented `pivot_longer` and `pivot_wider` instead of the previous verbs/functions that he used. Those can be found in the tidyr package and are probably the best reference which includes all of the learnings from years of user feedback. https://tidyr.tidyverse.org/articles/pivot.html","{""total_count"": 2, ""+1"": 2, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1310243385,feature request: pivot command,

| ballot_id | option_id | choice |
|-|-|-|
| 1 | 1 | 0 | 
| 1 | 2 | 1 |
| 1 | 3 | 0 |
| 1 | 4 | 1 |
| 2 | 1 | 1 |
| 2 | 2 | 0 |
| 2 | 3 | 1 |
| 2 | 4 | 0 |

and i want to reshape from this long form to this wide form:

| ballot_id | option_id_1 | option_id_2 | option_id_3 | option_id_ 4|
|-|-|-|-| -|
| 1 | 0 | 1 | 0 | 1 | 
| 2 | 1 | 0 | 1| 0 | 

i could do such a think like this.

```sql
select ballot_id, 
sum(choice) filter (where option_id = 1) as option_id_1,
sum(choice) filter (where option_id = 2) as option_id_2,
sum(choice) filter (where option_id = 3) as option_id_3,
sum(choice) filter (where option_id = 4) as option_id_4
from vote
group by ballot_id
