In this blog post you will find the slides that accompany my presentation at Bayes@Lund2018 (April 12th, 2018, Lund, Sweden). This is my first slide deck completely created in RStudio with the fantastic package xaringan, created by Yihui Xie. Hopefully I will not sound arrogant if I say that I am quite pleased with it. I spent a long time fiddling with the .css files in order to create a template containing the mandatory logos of Ghent University and the Faculty of Psychology and Educational Sciences.

In this blog post I will engage in something a bit more serious than playing with static or dynamic images (although, admittedly, it’s a lot of fun). I will show you my first attempt at analyzing a document using the wonderful tidytext package. tidytext allows to sort the constituent elements of a text (e.g., single words or n-grams) following Hadley Wickham’s tidy principles: each variable is a column; each observation is a row; each type of observational unit is a table.

In my first post I broke the ice by drawing mesmerizing Clifford attractors. My second post was supposed to be slightly more serious (e.g., something about data analysis, or what I think about the recent alpha wars), but I have not yet had the time… and my crippling perfectionism is surely not helping. So, what better way to procrastinate than to play with two of my favorite things in the world, R and our cat Borre1?
