根据R中另一个矩阵的内容填充矩阵

我想根据另一个矩阵的内容填充一个矩阵。以下是矩阵：

set.seed(135)
MAT1 <- replicate(6, sample(c("00", "01", "10", "11", "10"))); MAT1 <- t(MAT1)
rownames(MAT1) <- rep(letters[1:3], each = 2)
MAT1

  [,1] [,2] [,3] [,4] [,5]
a "00" "01" "10" "11" "10"
a "10" "00" "01" "11" "10"
b "10" "10" "00" "11" "01"
b "11" "10" "01" "00" "10"
c "10" "00" "01" "10" "11"
c "00" "10" "11" "01" "10"

LIST <- apply(X = MAT1, MARGIN = 2, FUN = unique)
MAT2 <- matrix(data = NA, nrow = 3, ncol = length(unlist(LIST)))
rownames(MAT2) <- c(letters[1:3]); colnames(MAT2) <- unlist(LIST)
MAT2 <- rbind(Hap = rep(1:length(LIST), lengths(LIST)), MAT2)
MAT2

    1  1  1  2  2  2  3  3  3  3  4  4  4  4  5  5  5
Hap 00 10 11 01 00 10 10 01 00 11 11 00 10 01 10 01 11
a   NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA
b   NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA
c   NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA

我们将“MAT1”按列拆分，循环

列表

，将

堆栈

后计数的

表

放入一个两列数据集中。然后循环遍历

列表的
名称
，并在'MAT2'中指定与提取的
列表
元素同名的列

lst1 <- lapply(asplit(MAT1, 2), function(x) as.data.frame.matrix(table(stack(x)[2:1])))
names(lst1) <- seq_along(lst1)
for(nm in names(lst1)) {
      MAT2[-1, colnames(MAT2) == nm] <- as.matrix(lst1[[nm]])
 }

数据
MAT1在循环之前，它工作得很好。但是，根据
lst1
，循环没有按预期填充
MAT2
。
lst1
的第二个（甚至其他）列表在
MAT2
@akrun中没有正确填写。多亏了您的回答，我找到了获得MAT2的方法。这有点差劲，但很管用
MAT2@AchilleNyouma可能是您的结构不同
lst1 <- lapply(asplit(MAT1, 2), function(x) as.data.frame.matrix(table(stack(x)[2:1])))
names(lst1) <- seq_along(lst1)
for(nm in names(lst1)) {
      MAT2[-1, colnames(MAT2) == nm] <- as.matrix(lst1[[nm]])
 }

MAT2

MAT1 <- structure(c("00", "10", "00", "11", "10", "11", "10", "11", "10", 
"10", "10", "01", "10", "00", "01", "01", "01", "10", "11", "01", 
"10", "10", "00", "10", "01", "10", "11", "00", "11", "00"), .Dim = 6:5,
.Dimnames = list(
    c("a", "a", "b", "b", "c", "c"), NULL))
