Analyzing NetHack data, part 1: What kills the players

Analyzing NetHack data, part 1: What kills the players

Abstract In this post, I will analyse the data I scraped and put into an R package, which I called {nethack}. NetHack is a roguelike game; for more context, read my previous blog post. You can install the {nethack} package and play around with the data yourself by installing it from github: devtools::install_github("b-rodrigues/nethack") And to use it: library(nethack) data("nethack") The data contains information on games played from 2001 to...

Getting the data from the Luxembourguish elections out of Excel

In this blog post, similar to a previous blog post I am going to show you how we can go from an Excel workbook that contains data to flat file.

Exporting editable plots from R to Excel: making ggplot2 purrr with officer

Exporting editable plots from R to Excel: making ggplot2 purrr with officer

I was recently confronted to the following problem: creating hundreds of plots that could still be edited by our client. What this meant was that I needed to export the graphs in Excel or Powerpoint or some other such tool that was familiar to the client, and not export the plots directly to pdf or png as I would normally do. I...

How Luxembourguish residents spend their time: a small {flexdashboard} demo using the Time use survey data

In a previous blog post I have showed how you could use the {tidyxl} package to go from a human readable Excel Workbook to a tidy data set (or flat file, as they are also called). Some people then contributed their solutions, which is always something I really enjoy when it happens. This way, I also get to learn things! @expersso proposed a...

However, when people use Excel for purposes it was not designed for, it can be a hassle. Often, people use Excel as a reporting tool, which...

The year of the GNU+Linux desktop is upon us: using user ratings of Steam Play compatibility to play around with regex and the tidyverse

I’ve been using GNU+Linux distros for about 10 years now, and have settled for openSUSE as my main operating system around 3 years ago, perhaps even more. If you’re a gamer, you might have heard about SteamOS and how more and more games are available on GNU+Linux. I don’t really care about games, I play the occasional one (currently Tangledeep) when...

Dealing with heteroskedasticity; regression with robust standard errors using R

Dealing with heteroskedasticity; regression with robust standard errors using R

First of all, is it heteroskedasticity or heteroscedasticity? According to McCulloch (1985), heteroskedasticity is the proper spelling, because when transliterating Greek words, scientists use the Latin letter k in place of the Greek letter κ (kappa). κ sometimes is transliterated as the Latin letter c, but only when these words entered the English language through French, such as scepter. Now that this is out of...
