Articles

Welcome to my blog! Its original title, “pars pas les mains vides!” which translates as “don’t leave empty-handed!”, conveys what I’m aiming to do: capture things I’ve picked up along the way in the weird and wonderful worlds of #rstats, data science and dataviz, and share them with others who may find them useful for their own adventures.

Feel free to pinch the best bits and reuse them for your own purposes - that’s what these articles are here for! And if you want to say thanks or hello, get in touch!

Ah, ha, ha, ha, Parameterise!

Dataviz

Parameterised plot

Coding tips

A workshop on creating parameterised plot functions, which allowed us to create plots with different data, different variables, and different styling, all from one function.

Parameterising a multi-part plot

Data visualisation

Parameterised plots

Today’s #rstats exercise in building parameterised plots is brought to you by my desire to avoid copy-pasting and making minor edits to 200+ lines of code in order to create two variants of a set of interactive graphs for a client. I decided to blog my way through the process to highlight a few tips and tricks I’ve picked up along the way.

“So much more than pretty graphs”: Recent adventures in automating dataviz solutions

The Data Lab Community - Women in Data and AI Meetup | I talked about dataviz design systems, parameterised plots and WebR, before enjoying a talk by Martina Pugliese, and joining her for a fireside chat with Ally Orr, to discuss how we ended up here and what we’re excited about.

A quick experiment with WebR: how much can I do in under an hour?

formatting

numbers

I got a leaflet through my door the other day with a bar graph that just didn’t look right. It inspired me to create a tool to easily create a bar graph online, so that people can do a quick side-by-side comparison. I’ve been wanting an excuse to give WebR a go, and this seems like a good place to start, so I thought I’d live blog my way through my first hour of playing with WebR. Ready, get set, go!

Formatting numbers for easy readability in R

Sometimes you want a raw number. Other times, you want a number that you can instantly verbalise. This post explores an easy solution for getting from “1234567890” to “1,234.6M” without installing any additional packages.

How to make data viz that matches your organisation’s branding

design

ggplot

Picking a colour scheme that ties in with a client’s brand or that evokes the subject matter behind the data is what allows datavisualisations to contribute to, rather than detract from, the main story the client is seeking to tell. This post covers both the design steps and the coding steps involved in creating bespoke colour schemes.

Setting up a generative art project using #rstats and GitHub Actions

generative art

github actions

For the last wee while, I’d been wanting to explore the fascinating field of Generative Art and add a continuous deployment project to my portfolio. Enter the @aRtfulBot, a Twitter bot I created to explore both of these at once!

Alignment cheatsheet

I’ve used {ggtext}’s geom_textbox() a lot in my recent data visualisations, but, every time, I end up resorting to a bit of trial and error to get the alignment just right. Time to create a cheatsheet that will be useful to my future self, and hopefully to a few others also.
