如果行名称与另一个 Dataframe 不匹配，如何将行值分配为0？

数据框架df.list的列表包含6个数据框架，列数相同，行数不同。
我希望所有的 Dataframe 具有相同的行数。如果行名不在 Dataframe 中（即即，唯一的），则将值赋值为0。 Dataframe 应该单独返回（而不是在列表中）。

df.list <- list(scores.1a, scores.1b, scores.1c, scores.2a, scores.2b, scores.2c)
unique.names <- Reduce(unique, lapply(df.list, row.names))

notin1a <- scores.1a[!(rownames(scores.1a) %in% unique.names),] 
scores.1a <- rbind(scores.1a, notin1a)
notin1b <- scores.1b[!(rownames(scores.1b) %in% unique.names),] 
scores.1b <- rbind(scores.1b, notin1b)
notin1c <- scores.1c[!(rownames(scores.1c) %in% unique.names),] 
scores.1c <- rbind(scores.1c, notin1c)
notin2a <- scores.2a[!(rownames(scores.2a) %in% unique.names),] 
scores.2a <- rbind(scores.2a, notin2a)
notin2b <- scores.2b[!(rownames(scores.2b) %in% common.names),] 
scores.2b <- rbind(scores.2b, notin2b)
notin2c <- scores.2c[!(rownames(scores.2c) %in% unique.names),] 
scores.2c <- rbind(scores.2c, notin2c)

回溯：

Error in cbind(scores.1a, scores.1b, scores.1c, scores.2a, scores.2b,  : 
  number of rows of matrices must match (see arg 2)

另一种方法使用match和replace。

uniq_rownames <- unique(as.vector(sapply(df.list, rownames)))

lapply(df.list, function(x){
  res <- x[match(uniq_rownames, rownames(x)),]
  res <- replace(res, is.na(res), 0)
  data.frame(res, row.names=uniq_rownames)})

您可以首先找到列表中所有 Dataframe 的最大行，然后使用lapply添加包含0的行（直到最大值），并使用索引跨越所有列。
使用简化数据以便于说明：

ll <- list(data.frame(a = 1:3, b = 1:3),
           data.frame(a = 1:7, b = 1:7))

您可以通过以下方式执行此操作：

maxrows <- max(unlist(lapply(ll, nrow)))

ll_same <- lapply(ll, function(x){if(nrow(x) < maxrows) x[(nrow(x)+1):maxrows,] <- 0; x})

输出：

[[1]]
  a b
1 1 1
2 2 2
3 3 3
4 0 0
5 0 0
6 0 0
7 0 0

[[2]]
  a b
1 1 1
2 2 2
3 3 3
4 4 4
5 5 5
6 6 6
7 7 7

如果你想让列表中的每个df在环境中都是自己的对象，可以使用assign：

# assign each df in the list to the environment
for(i in seq_along(ll_same)){
  assign(paste0("df_", i), ll_same[[i]])
}

为了使结果更明显，我简化了示例，但这也适用于完整数据。由于您实际使用的是matrix对象列表，因此我将其转换为data.frame，然后将每个集合中缺少的行赋值为0。
示例数据：

mat <- matrix(1:9, nrow=3, dimnames=list(letters[1:3], LETTERS[1:3]))
df.list <- list(mat[c(1,2),], mat[c(1,3),], mat[c(2,3),])

#[[1]]
#  A B C
#a 1 4 7
#b 2 5 8
#
#[[2]]
#  A B C
#a 1 4 7
#c 3 6 9
#
#[[3]]
#  A B C
#b 2 5 8
#c 3 6 9

处理它：

allrn <- Reduce(union, lapply(df.list, rownames))
df.list <- lapply(
    df.list,
    \(x) {
        x <- as.data.frame(x)
        x[setdiff(allrn, rownames(x)),] <- 0
        x[order(rownames(x)),]
    }
)

df.list
#[[1]]
#  A B C
#a 1 4 7
#b 2 5 8
#c 0 0 0
#
#[[2]]
#  A B C
#a 1 4 7
#b 0 0 0
#c 3 6 9
#
#[[3]]
#  A B C
#a 0 0 0
#b 2 5 8
#c 3 6 9
