该列表出了很多问题。从stackoverflow直接复制/粘贴到我的R控制台中不起作用...但是，当我将列表发布到R脚本中并运行该代码块时，将创建该列表。再次对庞大的数据表示歉意，但这对重现我的问题很有帮助...
从这里开始很简单。我通常使用以下函数取消嵌套任何JSON：
my.pbp.df <- my.pbp.data %>%
purrr::map(unlist) %>%
purrr::map(t) %>%
purrr::map(as_tibble) %>%
dplyr::bind_rows() %>%
readr::type_convert() %>%
as.data.frame()
...但是输出不正确。
我注意到的是，虽然map（unlist）将每个列表项转换为字符向量，而map（t）将每个列表项转换为矩阵，但是当我运行map（as_tibble）时，我丢失了该列矩阵中任何重复名称的项目的名称。我剩下的是一个填充有以下名称的数据框：
> colnames(this.periods.data)
[1] "id" "clock" "updated" "description"
[5] "event_type" "attribution.name" "attribution.market" "attribution.id"
[9] "attribution.team_basket" "location.coord_x" "location.coord_y" "on_court.home.name"
[13] "on_court.home.market" "on_court.home.id" "on_court.home.players.full_name" "on_court.home.players.jersey_number"
[17] "on_court.home.players.id" "V18" "V19" "V20"
[21] "V21" "V22" "V23" "V24"
[25] "V25" "V26" "V27" "V28"
[29] "V29" "on_court.away.name" "on_court.away.market" "on_court.away.id"
[33] "on_court.away.players.full_name" "on_court.away.players.jersey_number" "on_court.away.players.id" "V36"
[37] "V37" "V38" "V39" "V40"
[41] "V41" "V42" "V43" "V44"
[45] "V45" "V46" "V47" "possession.name"
[49] "possession.market" "possession.id" "V30" "V31"
[53] "V32" "V48" "V49" "V50"
[57] "statistics.type" "statistics.made" "statistics.shot_type" "statistics.team.name"
[61] "statistics.team.market" "statistics.team.id" "statistics.player.full_name" "statistics.player.jersey_number"
[65] "statistics.player.id" "statistics.rebound_type" "statistics.three_point_shot" "statistics.points"
[69] "V62" "V63" "V64" "V65"
[73] "V66" "V67" "V68"
所有V#列名实际上都应具有列名。例如，V18-V29之所以这样重命名，是因为它们实际上具有与前3列on_court.home.players.full_name, on_court.home.players.jersey_number, on_court.home.players.id完全相同的名称。运行map（as_tibble）时，这些名称会丢失。
简而言之，有没有一种更好的方法可以将列表/ JSON转换为数据框而不丢失列名？
谢谢！
编辑：所需的输出只是一组完整的列名。 V18应该是on_court.home.players.full_name.2，V19应该是on_court.home.players.jersey_number.2，V20应该是on_court.home.players.id.2，依此类推。而不是自动转换为无意义的V18 ，V19，V20，V21，V22等列，如果自动添加.x, .y或.2, .3, .4, etc.的重复列名称来做这些名称，那就太好了。

你可以做
df <- bind_rows(map(my.pbp.data, as.data.frame))
更简洁（多亏@RonakShah）
df <- map_dfr(my.pbp.data, as.data.frame)
检查列名给出
colnames(df)
