我目前的数据格式为每id正好有2行。我想将这些行折叠成一个单行,如下所示。我试过使用pivot_wider(),但它给了我太多的列。我只想要两个专栏。我如何才能做到这一点?

# current structure
tibble::tribble(
  ~id,   ~n,             ~prop, ~name, ~value,
  "1", 135L, 0.918367346938776,  "q1",    "Y",
  "1", 135L, 0.918367346938776,  "q2",    "Y",
  "3", 225L, 0.945378151260504,  "q1",    "Y",
  "3", 225L, 0.945378151260504,  "q3",    "Y",
  "5", 446L, 0.944915254237288,  "q1",    "Y",
  "5", 446L, 0.944915254237288,  "q4",    "Y"
)
#> # A tibble: 6 x 5
#>   id        n  prop name  value
#>   <chr> <int> <dbl> <chr> <chr>
#> 1 1       135 0.918 q1    Y    
#> 2 1       135 0.918 q2    Y    
#> 3 3       225 0.945 q1    Y    
#> 4 3       225 0.945 q3    Y    
#> 5 5       446 0.945 q1    Y    
#> 6 5       446 0.945 q4    Y

# desired structure
tibble::tribble(
  ~id,   ~n,             ~prop, ~name1, ~value1, ~name2, ~value2,
  "1", 135L, 0.918367346938776,  "q1",    "Y",   "q2",    "Y",
  "3", 225L, 0.945378151260504,  "q1",    "Y",   "q3",    "Y",
  "5", 446L, 0.944915254237288,  "q1",    "Y",   "q4",    "Y"
)
