JSONtoDataFrame: Extract the data from a JSON document as one (or several)...

In umatter/RWebData: A High-Level Interface to the Programmable Web

Description

Given JSON document, this function maps the potentially nested JSON data to one or several data frames. The data extraction algorithm applied in this function is based on the assumption that the JSON document describes either one or several entity types containing a set of observations described by different variables.

Usage

JSONtoDataFrame(x, alignVariables=FALSE)

Arguments

x	either a string containing JSON or the name of a file containing the JSON
alignVariables	logical, indicating whether variables/values should be rearranged in case the raw data was malformed (missing variable names)

Value

one data frame or a list of several data frames

Examples

JSON.ex <- system.file("exdata", "microcapital.json", package = "RWebData")
JSONtoDataFrame(JSON.ex, alignVariables=FALSE)
