I was reading an article about the results of our latest elections where I was having a look at the spatial pattern for votes in my city. I was wondering how would I go over obtaining the data for something like that and went to the Electoral Commission, which has this neat page with links…

I didn’t know where the data came from or how was the “index of disproportionality for each electorate” calculated, but I saw it mostly as an opportunity to whip up some quick code to practice the…

Functions with multiple results in tidyverse

Often I need to apply a function by groups of observations; sometimes, that function returns more than a single number. It could be something like for each group fit a distribution and return the distribution parameters. Or, simpler for the…

Turtles all the way down
One of the main uses for R is for exploration and learning. Let’s say that I wanted to learn simple linear regression (the bread and butter of statistics) and see how the formulas work. I could simulate a simple example and fit the regression with R:

I started using R ages ago and have happily lived in mostlybaseR for data manipulation. Once in a while I move to something that makes a big difference, like ggplot2 in 2010 or Rmarkdown in 2015, but the set of packages I use for data + plotting hasn’t seen many changes. I have to confess…
