Question

我从API提取了一份数据。数据具有多个嵌套列表。什么是清除此数据的有效方法？

作为参考，我正在尝试关注parsing json with purrr上的这篇文章，但是看来我的数据具有更多的嵌套列表，所以我在使用它时遇到了一些困难。

Answer 1

由于示例数据看起来非常简单。主列表中的每个对象仅包含一个唯一列表。您可以取消列出每个对象，将其转换为data.frame，然后将它们绑定在一起。

假设您的数据名为“ jsonRespParsed”：

games<-lapply(jsonRespParsed, function(game){data.frame(t(unlist(game)))})

library(dplyr)
answer<-bind_rows(games)


answer
#GameId Season SeasonType                 Day            DateTime Status AwayTeamId HomeTeamId AwayTeamName
#1  14491   2019          3 2019-04-14T00:00:00 2019-04-14T12:00:00  Final         11         14          NYI
#2  14492   2019          3 2019-04-14T00:00:00 2019-04-14T19:00:00  Final          6         16           TB
#3  14493   2019          3 2019-04-14T00:00:00 2019-04-14T19:30:00  Final         22         20          WPG
