  data=structure(list(ID_WORKES = c(119642709L, 119642709L, 119642709L,

119642709L, 119642709L), TABL_NOM = c(56220L, 56220L, 56220L, 
56220L, 56220L, 56220L, 56220L, 56220L, 56220L, 56220L, 56220L

1L), .Label = "nov", class = "factor"), ID_SP_NAR = c(1048L, 
1049L, 1050L, 1065L, 1066L, 1085L, 1086L, 1087L, 1088L, 1086L, 
1087L), KOD_DOR = c(92L, 92L, 92L, 92L, 92L, 92L, 92L, 92L, 92L, 
92L, 92L), KOD_DEPO = c(13283L, 13283L, 13283L, 13283L, 13283L, 
13283L, 13283L, 13283L, 13283L, 13283L, 13283L), COLUMN_MASH = c(0L, 
0L, 0L, 0L, 0L, 0L, 0L, 0L, 3L, 0L, 4L), x1 = c(0, 0, 0, 0, 0, 
0, 0, 0, 0.0625, 0, 0), x2 = c(0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 
2L, 0L, 0L)), .Names = c("ID_WORKES", "TABL_NOM", "NAME", "ID_SP_NAR", 
"KOD_DOR", "KOD_DEPO", "COLUMN_MASH", "x1", "x2"), class = "data.frame", row.names = c(NA, 
-11L))

我只需要使用COLUMN_MASH列，正如我们在这里看到的那样，只有两个值是整数（3和4），另一个值是零。如何为每个id_worker用column_mash中的最后一个值填充column_mash，即在所有行中必须为4。

如果最后一个值为0，则用先前的整数值填充列。

Answer 1

由于此问题被标记为data.table：

library(data.table)
setDT(data)
data[, COLUMN_MASH := last(COLUMN_MASH[COLUMN_MASH != 0]), by = ID_WORKES]

Answer 2

我们可以将53与ave一起使用，即

tail

将其分配回您的数据框以更新with(data, ave(COLUMN_MASH, ID_WORKES, FUN = function(i) tail(i[i != 0], 1))) #[1] 4 4 4 4 4 4 4 4 4 4 4，

COLUMN_MASH

Answer 3

在clock = pygame.time.Clock() while main == True: clock.tick(60) # [...]中，我们可以dplyr group_by并为每个ID_WORKES获得last的非零值。

ID_WORKES
