我有我试图“合并”在一起列出的清单。
尺寸是：
> dim(lst$`63908`$information)
[1] 1 19
> dim(lst$`63908`$filings)
[1] 27 11
> dim(lst$`793952`$information)
[1] 1 19
> dim(lst$`793952`$filings)
[1] 27 11
> dim(lst$`894405`$information)
[1] 1 19
> dim(lst$`894405`$filings)
[1] 27 11
我试图加入information和filings对于列表中的每个公司（或编号）。我要地图或加入information列表中filings列表，所以我将有1名列表中为每个公司和information列表会被重复27次这是filings列表的长度。我该如何进行呢？

以下是处理不同长度列表的答案：
library(tidyr)
library(purrr)
library(dplyr)
lst2$`1024125` <- NULL
lst2 %>%
map(function(x) {cbind.data.frame(x) %>% fill(everything())}) -> lst3
请注意，我正在丢弃列表1024125中的元素lst2。该列表元素包含一个没有列的空数据框。我认为您应该先整理数据，并确保所有这些数据框至少具有相同的列，即所有information数据框都具有相同的列，所有filings数据框都具有相同的列。
答案 2 :(得分：1)
如果存在NULL元素的情况，一种方法是分别pluck“信息”和“归档”，并用id列转换为单个data.frame并做一个full_join（假设'information'元素有1行或0行。
library(tidyverse)
map_df(lst2, pluck, 'information', .id = 'id') %>%
full_join(map_df(lst2, pluck, 'filings', .id = 'id'), by = 'id')
答案 3 :(得分：1)
请考虑一种基本的R解决方案，以与await knex('posts').insert({
title: faker.random.word(),
description: faker.lorem.paragraph(),
deleted: faker.random.boolean(),
createdAt: faker.date.recent(),
updatedAt: faker.date.recent()
})
一起提取所需的子列表和cbind项。然后是最后的Map外循环，用于单个最终数据帧输出。
由于归档文件中有空的数据帧，因此需要扩展函数处理程序来添加空列，以成功do.call(rbind, ...)附加到末尾。下面甚至使用子列表之一的名称创建一个ID列：
rbind
