Question

这是我的列表：

mylist<-
list(list(A = c(30, 50, 35, 25, 45), B = c(40, 35, 35, 50, 45
), C = c(40, 20, 40, 50, 25), D = c(35, 45, 45, 45, 40), E = c(20, 
30, 50, 45, 20), F = c(40, 40, 50, 30, 40)), list(A = c(50, 50, 
25, 40, 45, 40, 35, 40, 45, 20), B = c(40, 35, 40, 40, 45, 30, 
20, 50, 35, 25), C = c(20, 30, 50, 35, 45, 40, 25, 50, 35, 50
), D = c(20, 35, 30, 25, 40, 30, 50, 20, 25, 35), E = c(40, 25, 
25, 20, 50, 30, 50, 40, 35, 35), F = c(50, 20, 45, 35, 50, 45, 
30, 45, 35, 50)), list(A = c(45, 50, 25, 25, 30, 25, 35, 35, 
35, 30, 50, 50, 30, 30, 20), B = c(40, 20, 35, 35, 50, 20, 25, 
30, 35, 20, 40, 20, 45, 30, 20), C = c(50, 20, 25, 35, 35, 30, 
50, 25, 40, 35, 45, 45, 35, 45, 25), D = c(50, 50, 25, 35, 25, 
35, 20, 25, 45, 40, 35, 40, 50, 40, 30), E = c(50, 25, 20, 30, 
40, 45, 40, 50, 35, 40, 30, 45, 35, 50, 40), F = c(35, 50, 35, 
45, 25, 40, 50, 40, 50, 50, 50, 50, 35, 35, 40)), list(A = c(50, 
50, 50, 40, 20, 25, 50, 40, 50, 50, 45, 40, 30, 50, 35, 45, 50, 
30, 35, 45), B = c(45, 20, 25, 20, 25, 30, 20, 30, 45, 25, 50, 
30, 30, 25, 50, 45, 20, 45, 45, 50), C = c(20, 40, 50, 25, 40, 
45, 25, 30, 20, 20, 35, 45, 20, 40, 50, 45, 40, 40, 45, 35), 
    D = c(40, 40, 20, 25, 50, 50, 35, 45, 50, 45, 50, 35, 30, 
    40, 35, 45, 25, 45, 45, 25), E = c(20, 25, 35, 45, 35, 40, 
    40, 35, 35, 40, 30, 30, 40, 50, 25, 40, 30, 25, 20, 40)), 
    list(A = c(35, 25, 45, 20, 25, 30, 30, 35, 30, 40, 30, 20, 
    20, 30, 45, 40, 35, 35, 35, 35, 25, 45, 35, 20, 50), B = c(50, 
    35, 30, 30, 35, 45, 45, 50, 25, 25, 40, 25, 50, 45, 25, 30, 
    30, 25, 45, 45, 30, 20, 50, 30, 30), C = c(35, 40, 50, 25, 
    40, 45, 30, 25, 50, 25, 35, 50, 50, 50, 25, 50, 20, 50, 40, 
    25, 25, 35, 20, 20, 50), D = c(40, 35, 35, 40, 50, 35, 25, 
    40, 25, 25, 30, 45, 50, 35, 20, 50, 20, 20, 45, 50, 40, 30, 
    35, 50, 45), E = c(40, 25, 50, 50, 20, 50, 25, 50, 40, 30, 
    30, 50, 45, 45, 40, 45, 20, 20, 45, 35, 45, 50, 40, 40, 35
    ), F = c(40, 45, 35, 35, 30, 45, 40, 40, 20, 50, 50, 45, 
    40, 40, 45, 45, 35, 40, 20, 30, 35, 45, 30, 50, 25)))

我需要将所有“ A”元素发送到第一个列表位置（mylist[[1]]）。 “ A”元素为：mylist[[1]][[1]],mylist[[2]][[1]],mylist[[3]][[1]],mylist[[4]][[1]],mylist[[5]][[1]]。

然后，将所有“ B”元素移到第二个列表位置（mylist[[2]]）。 “ B”元素是：mylist[[1]][[2]],mylist[[2]][[2]],mylist[[3]][[2]],mylist[[4]][[2]],mylist[[5]][[2]]。

以此类推。

是否可以使用dplyr软件包来做到这一点？

purrr::transpose(mylist)

Answer 2

这是您要找的吗？

dplyr::bind_rows(mylist, .id = 'id')

# A tibble: 75 x 7
   id        A     B     C     D     E     F
   <chr> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
 1 1        30    40    40    35    20    40
 2 1        50    35    20    45    30    40
 3 1        35    35    40    45    50    50
 4 1        25    50    50    45    45    30
 5 1        45    45    25    40    20    40
 6 2        50    40    20    20    40    50
 7 2        50    35    30    35    25    20
 8 2        25    40    50    30    25    45
 9 2        40    40    35    25    20    35
10 2        45    45    45    40    50    50
# ... with 65 more rows

或者同一件事转换回list形式：

dplyr::bind_rows(mylist, .id = 'id') %>% as.list()

$id
 [1] "1" "1" "1" "1" "1" "2" "2" "2" "2" "2" "2" "2" "2" "2" "2" "3" "3" "3" "3" "3" "3" "3" "3" "3" "3" "3" "3" "3" "3" "3" "4" "4" "4" "4" "4" "4" "4" "4"
[39] "4" "4" "4" "4" "4" "4" "4" "4" "4" "4" "4" "4" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5" "5"

Answer 3

以防我使用base函数的变体：unlist和lapply

x <- unlist(mylist) #Turns mylist into a vector
res <- lapply(LETTERS[1:6], function(u) x[grep(u,names(x))]) #Filtering into a list the elements whose name is in the vector "A" through"F"
res <- lapply(res, unname) #To get rid of the created label names
names(res) <- LETTERS[1:6] #Names of the elements in the new list
res
$`A`
