Gosset part 2: small sample statistics

Scientific brewing at scale

Simulation was the key to to achieve world beer dominance. ‘Scientific’ Brewing at scale in the early 1900s Beer bottles cheers This post is an explainer about the small sample experiments performed by William S. Gosset. This post contains some R code that simulates his simulations1 and the resulting determination of the ideal sample size for inference. If you brew your own beer, or if you want to know how many samples you need to say something useful about your data, this post is for you. [Read More]

Quick post - detect and fix this ggplot2 antipattern

Recently one of my coworkers showed me a ggplot and although it is not wrong, it is also not ideal. Here is the TL:DR : Whenever you find yourself adding multiple geom_* to show different groups, reshape your data In software engineering there are things called antipatterns, ways of programming that lead you into potential trouble. This is one of them. I’m not saying it is incorrect, but it might lead you into trouble. [Read More]

Moving parts of a country over a map

I love making maps, I also love making gifs. In this short post I make an animated gif of parts of a map moving. In this case the parts of the map only move in the xy direction, but you can also turn them, and make them bigger or smaller. Today I show you how I made a part of the Netherlands ‘float away’. It is part of a larger nonsense project (I have many silly projects), and mostly just to document my path to learning about spatial analytics. [Read More]

Turning kindle notes into a tidy data

It is my dream to do everything with R. And we aRe almost there. We can write blogs in blogdown or bookdown, write reports in RMarkdown (thank you Yihui Xie!) create interactive webpages with Shiny (thank you Winston Chang). Control our lifx lights with lifxr (great work Carl!) and use emoticons everywhere with the emo package. There is even a novel of my vision! I recently found chapter 40 of A Dr. [Read More]
