Overview of this book

R is a powerful tool for statistics, graphics, and statistical programming. It is used by tens of thousands of people daily to perform serious statistical analyses. It is a free, open source system whose implementation is the collective accomplishment of many intelligent, hard-working people. There are more than 2,000 available add-ons, and R is a serious rival to all commercial statistical packages. The objective of this book is to show how to work with different programming aspects of R. The emerging R developers and data science could have very good programming knowledge but might have limited understanding about R syntax and semantics. Our book will be a platform develop practical solution out of real world problem in scalable fashion and with very good understanding. You will work with various versions of R libraries that are essential for scalable data science solutions. You will learn to work with Input / Output issues when working with relatively larger dataset. At the end of this book readers will also learn how to work with databases from within R and also what and how meta programming helps in developing applications.

Creating a dataset in PostgreSQL from R

The PostgreSQL database server can be accessed from R through the RPostgreSQL library. You can either create a new database, insert data into an existing database, or perform queries on the existing data tables. In this recipe, you will connect R with the PostgreSQL database server and create a table under the postgres database, and insert data into the database.

Getting ready

To connect with the PostgreSQL database server from R, you are required to install the RPostgreSQL library along with its dependencies. The following R code is to used install the necessary libraries to access the PostgreSQL database:

    install.packages("RPostgreSQL", dependencies = TRUE)

In this recipe...
