Question

我正在尝试从this page和与之关联的this is the specific json file检索数据。

我似乎无法提取有关设施的任何有意义的数据，似乎json文件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观众。第一个链接的文档页面似乎是XML格式。

Answer 1

从该网址获取数据：

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

现在您有一个名为my_dat的列表，内容为

> my_dat
$`@type`
[1] "dcat:Dataset"

$accessLevel
[1] "public"

$bureauCode
[1] "029:40"

$contactPoint
$contactPoint$`@type`
[1] "vcard:Contact"

$contactPoint$fn
[1] "Kevin Reid"

$contactPoint$hasEmail
[1] "mailto:vawebservices@med.va.gov"

如果这不是您期望的内容，那么这是数据源的问题。但这是一种从URL到R的摄取JSON的方法。
