Sometimes we need to extract text data from JSON file for our analysis.
A naive realization of JSON data in R maps JSON arrays to an unnamed list, and JSON objects to a named list. However, in practice a list is an awkward, inefficient type to store and manipulate data.
A matrix makes it easier to display data meaningfully across multiple dimensions -- it supports a stepped layout. The matrix automatically aggregates the data and enables drill down. You can create matrix visuals in Power BI Desktop reports and cross-highlight elements within the matrix with other visuals on that report page. For example, you can select rows, columns, and even individual cells.
Apart from converting JSON to R with fromJSON(), you can also use toJSON() to convert R data to a JSON format. In its most basic use, you simply pass this function an R object to convert to a JSON. The result is an R object of the class json, which is basically a character string representing that JSON. For this exercise, you will be working with a .csv file containing information on the.

The entry point into SparkR is the SparkSession which connects your R program to a Spark cluster. You can create a SparkSession using sparkR.session and pass in options such as the application name, any spark packages depended on, etc. Further, you can also work with SparkDataFrames via SparkSession.If you are working from the sparkR shell, the SparkSession should already be created for you.
