Lab9: R Data Interfaces

1 1. Introduction

In R, we can read data from files stored outside the R environment. We can also write data into files that will be stored and accessed by the operating system. R can read and write into various file formats like csv, excel, txt,rds, xml, json, etc.

2 2. Working Directory

Before we start working with data (interface data), first make sure your working directory in the right connection. You can check it by using the getwd() function. You can also set a new working directory using setwd() function.

print(getwd())               # get and print current working directory
