提取JSON数据库

我正在尝试从中检索数据，并与之关联

我似乎无法提取有关设施的任何有意义的数据，而且json文件似乎只是一个没有观察的描述

---

我正在尝试使用R包导入它。我试过JSON查看器。第一个链接中的文档页面似乎是XML格式的。

要从该url获取数据，请执行以下操作：

library(jsonlite) #install these if need be
library(curl)
my_dat <- fromJSON('http://catalog.data.gov/harvest/object/5630b80a-23dc-483f-8164-876dac1a9757')

---

如果这不是您期望的内容，那就是数据源的问题。但这是一种将JSON从URL摄取到R的方法。

很难理解您想要实现什么，但这可能会帮助您看到结构

jsonlite:：fromJSON（“http://catalog.data.gov/harvest/object/5630b80a-23dc-483f-8164-876dac1a9757“

我认为您需要更多地了解API，而

R

部分将很简单。
