Pimp my RMD: Tips for R Markdown – by Yan Holtz

Pimp my RMD: Tips for R Markdown – by Yan Holtz

R markdown creates interactive reports from R code, including interactive reports, documents, dashboards, presentations, and even books. Have a look at this awesome gallery of R markdown examples.

Yan Holtz recently created a neat little overview of handy R Markdown tips and tricks that improve the appearance of output documents. He dubbed this overview Pimp my RMD. Have a look, it’s worth it!

Harry Plotter: Shiny App of Spell Usage

Harry Plotter: Shiny App of Spell Usage

In my second Harry Plotter blog (22-Aug-2017), I wrote:

I would like to demonstrate how regular expressions can be used to retrieve (sub)strings that follow a specific format. We could use regex to examine, for instance, when, and by whom, which magical spells are cast.

Well, Prusinowskik (real name unknown) beat me to it, and how! S/He formed a comprehensive list of all spells found in the Harry Potter saga (see below), and categorized these into “spells“, “charms“, and “curses“, and into “popular“, “dueling” and “unforgivable” purposes. Next, Prusinowskik built an interactive Shiny application with lovely JavaScript graphs (package: rCharts) for us to discover precisely when during the saga which spells are cast (see also below). Moreover, the analysis was repeated for both the books and the movies.

Truly excellent work Prusinowskik! The Shiny app can be found here.

Beer-in-hand Data Science

Beer-in-hand Data Science

Obviously, analysing beer data in high on everybody’s list of favourite things to do in your weekend. Amanda Dobbyn wanted to examine whether she could provide us with an informative categorization the 45.000+ beers in her data set, without having to taste them all herself.

You can find the full report here but you may also like to interactively discover beer similarities yourself in Amanda’s Beer Clustering Shiny App. Or just have a quick look at some of Amanda’s wonderful visualizations below.

A density map of the bitterness (y-axis) and alcohol percentages (x-axis) in the most popular beer styles.

A k-means clustering of each of the 45000 beers in 10 clusters. Try out other settings in Amanda’s Beer Clustering Shiny App.

The alcohol percentages (x), bitterness (y) and cluster assignments of some popular beer styles.
