Data Analysis Using R Programming
Betram K.C. Chan · 2017
This chapter describes data processing and how computers perform the steps involved in turning data into information efficiently and effectively. It is indicated that many of these processing activities may be undertaken using R programming, or performed in an R environment with the aid of available R packages–where R functions and data sets are stored. To learn to do statistical analysis and computations, one may start by considering the R programming language as a simple calculator. In financial investigations, after preparing the collected data sets to undertake financial analysis, the first step is to enter the data sets into the R environment. Once the data sets are placed within the R environment, analysis will process the data to obtain results leading to creditable conclusions, and likely recommendations for definitive courses of actions to improve pertinent aspects of public and personal data. The chapter examines several methods for data set entry.
