rstudio::conf(2022) restrospective
It is the day after rstudio::conf(2022), and I’m sitting in the lobby of the ridiculously oversized conference hotel, trying to collect my thoughts and impressions. It was a densely packed two days of presentation and events (plus the earlier two days of workshops). Lots of new inspirations, ideas, impressions; all of which takes a little time ...

Counting Kaggle Followers through Meta Kaggle
This is a short post on how to count your followers on Kaggle, and who the current Kagglers are with the largest following. It also serves as preparation for my next blog post in which I will practice some network analysis on the table that we’ll create in this post. Kaggle, true to form as the home of data science and machine learning on the i...

A Kaggle Dataset of R Package History for rstudio::conf(2022)
It’s summer, and the long-awaited Rstudio conference for 2022 is only days away. Next week, a large number of R aficionados will gather in Washington DC for the first time in person since the beginning of the pandemic. A pandemic, mind you, that is far from over.

Tidy evaluation in R – Simple Examples
The tidyverse philosophy introduced by Hadley Wickham has been a game changer for the R community. It is based on intuitive rules of what a tidy data set should look like: each variable is a column, each observation is a row (Wickham 2014). At its core, the tidyverse collection of R packages is powered by a consistent grammar of data manipulation...

Data flow visuals – alluvial vs ggalluvial in R
I have long been a fan of creative data visualisation techniques. For me, the choice of visual representation is driven by both the type of data and the kind of question one wants to examine. The power of its visualisation tools has been a major strength of the R language well before the ggplot2 package and the tidyverse burst onto the scene. Tod...
