Question

我正在尝试在R中使用JSON文件，但是不幸的是，JSONlite在当前状态下无法读取JSON文件。对象（数组元素？）之间缺少逗号。我的目标是从几乎是JSON的文件中形成一个数据框架。以下是示例JSON文件，代码和结果。

[
{"Source":"ADSB","Id":43061,"FlightId":"N668XX","Latitude":44.000083,"Longitude":-96.654788,"Alt":4450} 
{"Source":"ADSB","Id":43062,"FlightId":"N683XX","Latitude":44.000083,"Longitude":-96.654788,"Alt":4450}
{"Source":"ADSB","Id":43063,"FlightId":"N652XX","Latitude":44.000083,"Longitude":-96.654788,"Alt":4450}
]

> jsondata = fromJSON("asdf.json")
Error in parse_con(txt, bigint_as_char) : 
  parse error: after array element, I expect ',' or ']'
          "Heading":280,"Speed":124}   {"Source":"ADSB","Id":43062,"Fl
                     (right here) ------^

在JSON文件中的对象之间插入逗号后，它没有问题。

{"Source":"ADSB","Id":43061,"FlightId":"N668XX","Latitude":44.000083,"Longitude":-96.654788,"Alt":4450}, 
{"Source":"ADSB","Id":43062,"FlightId":"N683XX","Latitude":44.000083,"Longitude":-96.654788,"Alt":4450},
{"Source":"ADSB","Id":43063,"FlightId":"N652XX","Latitude":44.000083,"Longitude":-96.654788,"Alt":4450},
]

> jsondata = fromJSON("asdf.json")
> names(jsondata)
[1] "Source"    "Id"        "FlightId"  "Latitude"  "Longitude" "Alt"

如何在所有弯曲括号之间的整个JSON文件中插入逗号？（即“} {”->“}，{” 还是R有另一种方式读取我不完整的JSON文件？

我还不是新手，所以非常感谢您的帮助！

R中是否有一种方法可以将逗号添加到不正确的JSON格式？
