Posted on by Iwan Luijks. Keywords: R, RODBC, MySQL, Windows

Every now and then I want to gather some specific information from my databases, e.g. what the probability is of new visitors showing up during a certain season. This could be for example both interesting for determining upcoming serverload and bandwidth usage as well as other things.

For gathering this information I use R, a very powerful language for doing all sorts of analysis on all sorts of data. It is besides my use case for example also used for analysis of genomic data.

In this blog post I'll keep it simple, and give you a kickstart by showing you how to connect to a MySQL-server via ODBC with R. When connected, you can start analysing your data, this however is something I don't cover in this post.

There are a lot of data sources available for us to use and every company and consumer has its own opinion about which one to use, which can even differ per type of usage, application or website. Therefore a lot of database adapters exist for R; one of these adapters is RMySQL, packaged as the RMySQL package.

This post describes the installation of the RMySQL package from beginning to end, assuming you have a 32-bit Windows 7 machine ready.
