我有大量来自和API的JSON文件，它们的格式与我需要组合和/或转换为R中的数据帧的格式相同。我尝试了许多不同的方法来执行此操作，但是JSON文件嵌套，无法正常工作。是否有可能做到这一点？
以下是我尝试过的几个示例：
data_all <- data.frame()
for(i in 1:nrow(sov_w_add_URL)){
response <- GET(call[i], add_headers(Authorization = "Token token=some_token_here"))
response_txt <- content(response, "text")
data <- fromJSON(response_txt)
write_json(data, paste("respones",i,".json", sep=""))
}
mydata <- fromJSON(file = "respsones1.json")
mydata_table <- data.frame(mydata)
for(i in 1:nrow(sov_w_add_URL)){
json_temp <- lapply(files, function(f) fromJSON(files = paste("respones",i, sep="")))
json_final <- toJSON(json_temp)
write_json(json_final, "json_final")
}
或者，我也尝试过：
data <- fromJSON(file = "respones1.json")
json_data <- as.data.frame(data)
在两种情况下，我都会遇到类似的错误：
Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, : arguments imply differing number of rows: 1, 0
根据注释的要求，这是JSON文件：
