我尝试阅读 JSON来自 R 的文件使用 rjson但不断收到错误。我使用各种在线验证器验证了 JSON 文件。这是 JSON 文件的内容:

{
"scenarios": [
{
"files": {
"type1": "/home/blah/Desktop/temp/scen_0.type1",
"type2": "/home/blah/Desktop/temp/scen_0.type2"
},
"ID": "scen_0",
"arr": [],
"TypeToElementStatsFilename": {
"type1": "/home/blah/Desktop/temp/scen_0.type1.elements",
"type2": "/home/blah/Desktop/temp/scen_0.type2.elements"
}
}
],
"randomSeed": "39327314969888",
"zone": {
"length": 1000000,
"start": 1
},
"instanceFilename": "/home/blah/bloo/data/XY112.zip",
"txtFilename": "/home/blah/bloo/data/XY112.txt",
"nSimulations": 2,
"TypeTodbFilename": {
"type1": "/home/blah/bloo/data/map.type1.oneAmb.XY112.out"
},
"arr": {
"seg11": {
"length": 1000,
"start": 147000
},
"seg12": {
"length": 1000,
"start": 153000
},
"seg5": {
"length": 1000,
"start": 145000
},
"seg6": {
"length": 1000,
"start": 146000
},
"seg1": {
"length": 100,
"start": 20000
}
},
"outPath": "/home/blah/Desktop/temp",
"instanceID": "XY112",
"arrIds": [
"seg5",
"seg6",
"seg1",
"seg11",
"seg12"
],
"truth": {
"files": {
"type1": "/home/blah/Desktop/temp/truth.type1",
"type2": "/home/blah/Desktop/temp/truth.type2"
},
"ID": "truth",
"TypeToElementStatsFilename": {
"type1": "/home/blah/Desktop/temp/truth.type1.elements",
"type2": "/home/blah/Desktop/temp/truth.type2.elements"
}
}
}

和错误:
> json_file <- "~/json"
> json_data <- fromJSON(paste(readLines(json_file), collapse=""))
Error in fromJSON(paste(readLines(json_file), collapse = "")) :
unexpected character: :

最佳答案

RJSON 对空数组感到害怕。

fromJSON( '{ "arr": [ ] }')



fromJSON("{\"arr\": [ ] }") 中的错误:意外字符::
