带有dataframes的R列表在整个输出中都有名称，但是没有单独的名称

认为我不必为重现的例子做出示例，因为我认为这只是一种现象..或命名法？算法？我不知道。抱歉，我是R的新手。

我有数据范围的列表。也许是二维？ [[67]] [3]。

列表本身在结构上有67行，所以

length(example_DF)

给了我67个。当然。

这67个大房间（？人们总是将[[n]]的概念解释为一个大房间，所以...）

有三个小房间。 1

length(example_DF[[1]])

3。

这三个小房间名称是

names(wholeData_Merged_Splitted[[1]])

'0''1''2'

[[n]] [m]）是一个单个dataframe 94 x 11，也是

length(example_DF[[1]][1])

。

一个小房间（大房间确实在控制台输出中有名字。

example_DF

1.$'0'
(dataframe output which is the same as [[1]][1])
$'1'
(dataframe [[1]][2])
$'2'
(dataframe [[1]][3])
2.$'0'
(dataframe [[2]][1])
$'1'
(dataframe [[2]][2])
$'2'
(dataframe [[2]][3])

... 

67.$'0'
(dataframe [[67]][1])
$'1'
(dataframe [[67]][2])
$'2'
(dataframe [[67]][3])

我认为这是完全正常的。

但是，当我尝试查看整个示例_DF数据框架时，名称值为null。

names(example_DF)

NULL

我期望'1''2''3'...'67'。那个完整的输出说明了这一点。但是为什么..？

我也尝试了Rownames（），但结果是相同的空值。

在文档中，返回函数name（）的值是的字符向量，其长度与x或null 相同。然后是[[n]]名称确实是null值，但是输出必须有一些数字，所以我得到了1。 2。... 67。即时？

原文

Think I don't have to make reproducible examples because I think it's just a phenomenon..?or nomenclature? algorithm? that I don't know. sorry i'm new to R.

I have a list of dataframes. maybe 2-dimension? [[67]] [3].

the list itself structually has 67 rows, so

length(example_DF)

gives me 67. of course.

and each of these 67 big rooms(? people always explan the concept of [[n]] as a big room, so...)

have three small rooms. so

length(example_DF[[1]])

is 3.

those three small room names are

names(wholeData_Merged_Splitted[[1]])

'0''1''2'

one small room([[n]][m]) is a single dataframe 94 x 11, so

length(example_DF[[1]][1])

is 1.

I printed the whole example_DF and those 67 big rooms did have names in the console output.

example_DF

1.
This is totally normal I think.
But when I tried to have a look at the whole example_DF dataframe, the name values are NULL.
names(example_DF)

NULL

I expected '1' '2' '3' ... '67'. That full output says that. but why is it..?
I tried rownames() also, but the result is the same NULL value.
In the docs, return value of the function names() is a character vector of up to the same length as x, or NULL. Then is the [[n]] name is really NULL value but the output had to have some numbers so I got 1. 2. ... 67. instantlly?
