Recipe Objective

JSON stands for JavaScript Object Notation. .JSON file is in a text file format which is interchagable and primarily used for data transmission between server and web apps. It is easy to understand and self describing.

In this recipe we will discuss how to write a JSON file through R

Step 1: Installing and loading the required package

We use "rjson" package to write json files

install.packages("rjson") library(rjson)

Step 2: Creating a list of objects

We create a list of objects using vector() function

Syntax: vector(mode, length)

where:

  1. mode = "list" if we are interested in creating lists;
  2. length = the number of lists it can store
list_1 = vector(mode="list", length = 2) ‚Äč # assigning different objects to the list list_1[[1]] = c("Rick","Dan","Michelle","Ryan") list_1[[2]] = c("623.3","843.25","578","722.5")

Step 3: Writing a JSON file

First we read the above list to JSON. We use toJSON function to do so.

myfile = toJSON(list_1)

Writing the JSON object created to a file named "myJSON". We use write() function to do so.

write(myfile, "myJSON.json")
