R 如何将两个数据帧转换为一个自定义列表文件

我有两个数据帧，我想将它们合并到一个列表文件中 我的第一个数据帧是

 df1 <-structure(list(Countries = structure(c(4L, 2L, 7L, 3L, 6L, 5L, 
1L), .Label = c("Argentina", "Bangladesh", "Germany", "India", 
"Italy", "Spain", "USA"), class = "factor"), score = c(5L, 3L, 
3L, 36L, 27L, 38L, 42L), prescore = c(14L, 2L, 9L, 30L, 23L, 
28L, 30L), Here = c(1.654426641, 0.317580534, 1.198132543, 1.159607938, 
0.502336763, 0.258959426, 3.590781184), There = c(0.929521231, 
0.263531469, 0.856353826, 1.492219621, 0.446449268, 0.295339446, 
2.365211352), Thevalue = c(1.309899094, 0.165288467, 1.150147005, 
1.622165884, 0.528522213, 0.634062442, 1.733429701)), .Names = c("Countries", 
"score", "prescore", "Here", "There", "Thevalue"), class = "data.frame", row.names = c(NA, 
-7L))

有些人回答为列表（df1，df2），但如果我这样做，它会将第一个转换为因子

看看这里，我想要什么

---

..$countries:chr[1:7]“巴西”、“荷兰”、“美国”和“英国”..

正如上面评论中所提到的

列表（df1、df2）

完成了这项工作。抱歉，我忽略了所需的输出。继续执行以下步骤

df1$Countries <- as.character(df1$Countries)
df2$Countries <- as.character(df2$Countries)

---

df1$Countries考虑将每个数据帧强制转换为list（）函数中的列表：

df_list <- list(as.list(df1),as.list(df2))
df_list

df_list@d.b如果我这样做，那么第一个factor@d.b谢谢你解决了这个问题，我非常感激，谢谢你的教导me@d.b只有一件事。如何使df1和df2出现在列表中？查看输出列表df1:'data.frame'：@d.b很抱歉打扰您，但是如何将此添加到列表（df1，df2）中，这不是期望的结果。只需一件事，我接受您的答案。如何使df1和df2出现在列表中？查看输出列表df1:'data.frame'：这是
str（）
命令的输出，我已经更新了答案以响应您的评论
df1$Countries <- as.character(df1$Countries)
df2$Countries <- as.character(df2$Countries)

result <- list(df1, df2)
str(result)

df_list <- list(as.list(df1),as.list(df2))
