我在将 JSON 转换为数据帧时遇到了问题。我尝试使用库:jsonlite , RJSONIO , rjson .
我不断收到“字符串中的无效字符”或未关闭的字符串。
我从标准 API 获取此数据，因此应该能够解析此 json。此外，JSON 编辑器可以很好地解析这些数据。
我的问题是:
是否有一种标准方法可以确保我的数据帧被创建并忽略上述错误？
我最好的猜测是使用 toJSON 将此数据转换为 JSON 格式。来自任何一个库的函数，但如果我使用
newdata <- fromJSON(toJSON(data))
它以某种方式永远不会转换为数据帧。这是为什么？
如果我改为使用
newdata <- fromJSON(data)
我得到了一个有效的数据帧，但有时由于上述错误，它不起作用，这正是我想知道的。你如何处理这个问题？
我也试过用这个 freshDeskTicketsToDF <-
jsonlite::fromJSON(paste(readLines(textConnection(freshDeskTickets)), collapse=""))
在 R 中有没有更好的方法来处理这个问题？
编辑:当我有
<html tags> 时，我似乎收到此错误在我的“字符串数据”中，但我在我的 JSON 数据中都有它们，而且我不是每次都得到它。遇到这样的问题怎么办？
注意:此问题并非特定于我拥有的数据。我正在寻找的是处理此类问题的方法，而不是针对单个问题的特定解决方案。

最佳答案
library(jsonlite)
df <- stream_in(file("~/data/sample.json"))
stream_in函数直接转换为dataframe
