Big Data Analytics with R

By: Simon Walkowiak

Overview of this book

Big Data analytics is the process of examining large and complex data sets that often exceed the computational capabilities. R is a leading programming language of data science, consisting of powerful functions to tackle all problems related to Big Data processing. The book will begin with a brief introduction to the Big Data world and its current industry standards. With introduction to the R language and presenting its development, structure, applications in real world, and its shortcomings. Book will progress towards revision of major R functions for data management and transformations. Readers will be introduce to Cloud based Big Data solutions (e.g. Amazon EC2 instances and Amazon RDS, Microsoft Azure and its HDInsight clusters) and also provide guidance on R connectivity with relational and non-relational databases such as MongoDB and HBase etc. It will further expand to include Big Data tools such as Apache Hadoop ecosystem, HDFS and MapReduce frameworks. Also other R compatible tools such as Apache Spark, its machine learning library Spark MLlib, as well as H2O.

PostgreSQL with R on Amazon RDS

The methods for launching various open-source SQL databases described in the preceding two sections present just one way of connecting R to data stored in these databases. An alternative approach is offered by Amazon RDS - a managed and highly-scalable solution for database management. In fact, Amazon RDS is probably the easiest and fastest method of deploying a fully-operational SQL database, as it requires very minimal input from users. It also allows support for remote connectivity from RStudio, ensuring that users can quickly connect to the database in the cloud from the comfort of their local computer.

Launching an Amazon RDS database instance

Setting up and launching the database instance on Amazon RDS is generally very user friendly. The following instructions will guide you through the process and will let you create a small, Free Usage Tier (as of April 2016) t2.micro RDS instance with a PostgreSQL database ready for use:
