Однако он не работает с таблицей данных, но работает с данными. Кадр, в чем проблема и как ее решить .

data.table(time = x)
data.frame(time = x)

Error in dimnames(x) <- dn : length of 'dimnames' [1] not equal to array extent

Answer 1

Вот один из способов представить эту информацию в data.table

as.data.table(lapply(setNames(slotNames(x), slotNames(x)), slot, object = x))
#      .Data year month day hour minute
#   1:    29    0     0   0    1      5
#   2:     6    0     0   0   14      6
#   3:    48    0     0   0    0     53
#   4:    10    0     0   0    3     40
#   5:    44    0     0   0    7      0
#  ---                                 
# 104:    33    0     0   0    7     59
# 105:     3    0     0   0    2     48
# 106:    47    0     0   0    0     11
# 107:    26    0     0   0    7     41
# 108:    42    0     0   0    1     25

Answer 2

Вы можете попробовать преобразовать в as.duration, если хотите позже выполнить математические вычисления в столбце.

data.table(as.duration(x))
                        V1
  1:   3929s (~1.09 hours)
  2:  50766s (~14.1 hours)
  3: 3228s (~53.8 minutes)
  4:  13210s (~3.67 hours)
  5:  25244s (~7.01 hours)
 ---                      
104:  28773s (~7.99 hours)
105:   10083s (~2.8 hours)
106: 707s (~11.78 minutes)
107:  27686s (~7.69 hours)
108:   5142s (~1.43 hours)

Answer 3

Это атрибуты, создающие проблему. Если мы можем преобразовать в character, это будет работать

data.table(time = as.character(x))

Или другой вариант - создать list столбец

data.table(time = list(x)) 

Или получить компоненты, можно использовать @

data.table(.Data = x@.Data, year = x@year, month = x@month, 
      day = x@day, hour = x@month, minute = x@minute)

---

Или создать tibble

library(tibble)
tibble(x)
