Capital Circles

I really enjoyed seeing other’s #30DayMapChallenge posts, and particularly those of Ansgar Wolsing. I spent a while thinking about this glorious post

Data Quest: Motorway Services UK

I’m working on a few ideas about Motorway Service Stations in the UK, or more specifically the mainland of Great Britain (England, Scotland and Wales). However, I was…

{highcharts} doesn’t like empty factors (and the .by argument is quite nice, actually)

Creating an R-Ladies quarto format

It’s the day after rstudio::conf(2022), and like many folks in the audience I’m very excited about the future of {quarto}. (LINKS). To help me better understand the…

Overriding individual code chunk options

I’ve just moved this entire blog from {blogdown} to {quarto}. It was mostly simple but for one of the blogposts I really wanted a way to override individual code chunk…

Writing verbatim SQL in pipe chains using {dbplyr}

I’ve been trying to use the {dbplyr} package when working with SQL and R. It provides a really nice interface for writing tidyverse code against a database connection. I…

In this blogpost I use crawling the internal links between pages in the University of Oxford’s Research Data website as an excuse for finally getting to grips with tidygraph and ggraph

Recipes for learning

dataviz

In this blogpost I introduce one of my favourite datasets, a treasure trove of 57,000+ recipes scraped from recipe websites for a fascinating research paper (DOI: 10.1038/srep00196) comparing how different cuisines choose ingredients. I first used this dataset in May 2015 to learn how to use R and continue to use it to test my understanding of new techniques and analysis.

dataviz

If you’ve never heard of them, htmlwidgets are an amazing part of the work that RStudio (plus ramnathv and timelyportfolio) have undertaken to make R a beautiful tool for doing data science and communicating things about your data. Using leaflet, plotly, highcharter and more it’s possible to create rich interactive charts, maps and other visualisations directly from R without having to learn JavaScript
