Cleaning the data

Data cleaning, or rather tidying up the data, is the process of transforming raw data into specific consistent data that includes analysis in a simpler manner. The R programming language includes a set of comprehensive tools that are specifically designed to clean the data in an effective manner. We will be focusing here on cleaning the dataset in a specific way:

Include the libraries that are needed for cleaning and tidying up the dataset:

> library(dplyr)
> library(tidyr)

Analyze the summary of our dataset, which will help us to focus on which attributes to use:

>summary(longley)
