Is there a way to import data from a JSON file into R? More specifically, the file is an array of JSON objects with string fields, objects, and arrays. The RJSON Package isn't very clear on how to deal with this http://cran.r-project.org/web/packages/rjson/rjson.pdf.

推荐答案

首先安装 rjson 软件包:

First install the rjson package:

install.packages("rjson")

然后:

library("rjson")
json_file <- "http://api.worldbank.org/country?per_page=10&region=OED&lendingtype=LNX&format=json"
json_data <- fromJSON(paste(readLines(json_file), collapse=""))

更新:自0.2.1版起

json_data <- fromJSON(file=json_file)
