Конвертировать JSON в CSV в R: загружает только один ряд

Question

Привет! Я использую приведенный ниже код для преобразования файла json в csv.

library(rjson)
data1 <- fromJSON(file="Desktop/myfulldata.json")
j_data <- as.data.frame(data1)
write.csv(j_data, "my4.csv",row.names=FALSE)

мой файл json содержит:

[{"Status":"COMPLIANT","InstalledTime":"","ExecutionType":"","PatchSeverity":"","Title":"","Severity":"UNSPECIFIED","ExecutionTime":"2019-05-22T12:46:53Z","captureTime":"2019-05-22T12:46:58Z","schemaVersion":"1.0"},
{"Status":"COMPLIANT","InstalledTime":"2014-03-18T00:00:00.0000000Z","ExecutionType":"Command","PatchSeverity":"Critical","Title":"Windows (KB2919355)","Severity":"UNSPECIFIED","ExecutionTime":"2019-05-22T11:56:58Z","captureTime":"2019-05-22T12:46:58Z","schemaVersion":"1.0"},
{"Status":"COMPLIANT","InstalledTime":"2014-10-15T00:00:00.0000000Z","ExecutionType":"Command","PatchSeverity":"Important","Title":"Security (KB2977765)","Severity":"UNSPECIFIED","ExecutionTime":"2019-05-22T11:56:58Z","captureTime":"2019-05-22T12:46:58Z","schemaVersion":"1.0"}]

В моем файле много строк, но выводэто только один ряд.Что я делаю не так?

Пример взят из документации пакета jsonlite (пакет используется в httr для обработки jsons):

library(jsonlite)
# Stringify some data
jsoncars <- toJSON(mtcars, pretty=TRUE)
cat(jsoncars)

# Parse it back
fromJSON(jsoncars)

# Parse escaped unicode
fromJSON('{"city" : "Z\\u00FCrich"}')

РЕДАКТИРОВАТЬ : с предоставленными данными:

# --- with provided data
library(jsonlite)
dframe <- jsonlite::fromJSON(txt = "question_so_json.json")
dframe

# Run this to write csv
utils::writes.csv(x = dframe, file = "mydata.csv")

данные

        "Status":"COMPLIANT",
        "InstalledTime":"",
        "ExecutionType":"",
