Exploratory Data Analysis – All Blog Posts on The Chemical Statistician

(This article was first published on The Chemical Statistician » R programming, and kindly contributed to R-bloggers)

This series of posts introduced various methods of exploratory data analysis, providing theoretical backgrounds and practical examples.  Fully commented and readily usable R scripts are available for all topics for you to copy and paste for your own analysis!  Most of these posts involve data visualization and plotting, and I include a lot of detail and comments on how to invoke specific plotting commands in R in these examples.

I will return to this blog post to add new links as I write more tutorials.
