fromjson与不同的行

Question

我试图一次性转换带有R的json文件。不幸的是，这种方法给我一个错误，如下所述：

> fromJSON(res.clean[,2])
Error: parse error: trailing garbage
          :{"b64_value":"AAAAAA=="}}}] [{"loc":[{"N":9.03553},{"N":45.
                     (right here) ------^

如果相反我一行一行，一切都很好

> fromJSON(res.clean[1,2])
                 loc  recorded_at fields.b64_value fields.b64_value fields.b64_value

有没有办法做同样的事情我一个接一个地做？我想避免运行for循环

for (i in 1:max){
fromJSON(res.clean[i,2])}

非常感谢你的帮助
