In which the author realises she doesn’t know how to write package release posts
The 2020 ABS standard for collecting sex and gender data is almost never the right approach outside the context it was designed for, and its spread into medicine and other…
You will be shocked to learn that this is not actually a post about cocaine
There is very little novelty in this one, but it helps me to have it written down somewhere
More precisely, some thoughts on an R package I might send to CRAN, and I’d appreciate comments and criticism
Wherein the author attempts to convince herself that she hasn’t just been imagining things
Some notes on managing multiple sets of github credentials on the one machine
An area of statistics in which the author is not strong, and really needs to up her game
For the love of fuck, literally nobody thinks that 20% of the population is transgender. Please stop sharing that ridiculous YouGov statistic
Kind of a generative art thing, but mostly an attempt by the author to prove to herself that a she can write a short blog post without turning it into a goddamn monograph
Fiiiiiiinally she writes the cursed GAMLSS post. Oh and it’s also about the NHANES data set I guess
No, I do not care about splines. But I am trying to learn about GAMLSS regression, and yes, it is to this dark place that this topic has taken me
This is so obviously a prequel post to something else that I want to write about GAMLSS models
To quote Cassian Andor, “It’s harder than it looks”
A little bit like the book chapters, except with fewer details about things you care about, and several weird digressions that nobody will love
As with so many things in life, something that I used to think was infuriatingly difficult and cumbersome turns out to be really easy if you just format the data properly
Multivariate normal sampling can be wildly irreproducible if you’re not careful. Sometimes more than others. There are eldritch horrors, ill-conditioned matrices, and…
In which the author calls the little mermaid a whore
In which our intrepid adventurer turns a hacky data visualisation exercise into an analysis pipeline; builds an R blog with litedown and targets; and tries to wrap her head…
Code and explanations for a Tidy Tuesday data visualisation exercise
An introduction to the ggfx package. Some weirdly distorted images are created. Good times are had by all concerned
There are a lot of rectangles in this post. Also some foolishness with voronoi tessellations I guess
A deep dive into the fractal flame algorithm, an egregious coding error, and a lot more C++ than I would prefer to be writing
Let’s be honest, this entire post is a thinly-veiled excuse to play around and do terrible things with the rayshader package
It’s almost offensive how much you can do with 500 nearly-transparent polygons
Fun and games with spatial noise patterns, courtesy of the ambient package
An act of wholesale, unapologetic theft. In which the author discusses the core logic of generative art, and (ab)uses the ggplot2 package for her own ungodly purposes
Now I have \2 problems
What sins will she commit?
In which the author sighs a lot
Let’s be honest… I wrote this post because I wanted an excuse to be sweary. But I guess it’s also a post about interacting with the file system in R
In which the author explores the flextable R package for table construction, and gushes far too much about the work of Iain M. Banks
A pretty reckless dive into a package that hits the sweet spot for me
Part three of this three-part series of Julia posts, in which I try to figure out how to draw some nice plots
Part two of a three-part series on Julia, in which the author teaches herself the basics of wrangling rectangular data in Julia
Part one of a three-part series in which I swear I was going to keep it brief but ended up writing a staggeringly long set of notes on learning a bit of Julia
There might be a darker undercurrent in this one
How to make a mess with ggplot2 and ambient
A post that is little more than notes-to-self, on a model I want to make sure I understand
I’ve used observable.js before, but this time around I actually tried to understand how it works
Customising knitr output with hook functions is a handy skill, and I can never quite remember it when I need to, so here’s a blog post to remind myself
In which the author was trying to fuck a spider but ended up shaving a yak with a fabulous Dua Lipa soundtrack in the background
Because you know what? I am here to fuck spiders
There are times when you simply have to derive a thing yourself in order to understand it, even if no-one else cares
Some say the year ends in fire, some say in ice. As to my own desire, any end at all will be nice.
Basically the same post as the last one. It’s a brief introduction to pharmacometric simulation, but this time I’m using rxode2 instead of mrgsolve
Yet another post in the ever-expanding series where Danielle teaches herself pharmacometric modelling, which I’m certain is thrilling to everyone
It’s not 50 ways to leave your lover, but spend enough time talking about assertive programming in the bedroom and you’ll only have 49 more to discover
Another small step along the path to Bayesian pharmacometrics
Setting up nice developer environments on a Windows / Ubuntu-for-WSL system with the help of RStudio Server and the VS Code WSL extension
Fly, you fools!
Something nicer than the last post
Estimating the number internally displaced transgender people in the United States.
Fun and games with asciicast and cli. There’s really not much to this one except a little bit of personal entertainment
Learning my lessons the hard way
In which the author works her way through the first part of an online tutorial, rewrites some NONMEM code in Stan, and takes notes
A book review, sort of. Not really. Look, Greg sent me a copy and I had fun reading it. okay?
On the small joys of clean, single-purpose R packages.
A discussion of one- and two-compartment pharmacokinetic models with model implementations in Stan, covering both first-order dynamics and Michaelis-Menten kinetics.
A heavily oversimplified discussion of a simple pharmacokinetic tool, written as an exercise in teaching myself something new. Learning new things is always fun
In which the dead return to life and the author has opinions
A note that I wrote for a computer science class I taught all the way back in 2010
In which the author gets unreasonably excited about a new thing
I decided it was time to learn more about the grid package in R, and so naturally used it to make generative art
Using ambient and rayshader to create weird, broken landcape images in R
Okay it’s a short post in which I teach myself a bit of p5.js, but it does have five different donut examples which seems cool?
In which it is painfully clear that the author is trying to figure it all out as she goes
In which the author learns how to use docker and, in her usual fashion, goes a little bit overboard. But there are also generative art whales, so that’s nice.
There is no reason for this.
A wrap up of my 2022. Even by the standards of the recent past this has been a very weird year for me. A lot has happened, both professionally and personally. I’m still…
It is a truth universally acknowledged, that a post about multithreading must be in want of an async trick
Am I bored in the house? Yes. And am I in the house bored? Also yes. But do I have rvest and a stubborn desire not to allow the horrors of ‘data encoded in the CSS style’ to…
A comment on how Datasets work in Apache Arrow. I’m not really sure who the audience for this one. Am I just talking to myself? Probably.
A hastily written guide for data science folks trying to navigate the fediverse.
A step by step walkthrough introducing the reader to Arrow Flight, with examples in R and Python
A Pythonic approach for sharing Arrow Tables between Python and R. This is the second in a two-part series on data transfer. In this post I discuss how the rpy2 Python…
In a multi-language ‘polyglot’ data science world, it becomes important that we are able to pass large data sets efficiently from one language to another without making…
Resolving a little quirk in managing packages with pak on linux
In which the author grapples with the awkward question of what data visualisation really means when you have a staggering amount of data to work with
In which the author discusses arrays, chunked arrays, record batches, tables, and datasets in the R interface to Apache Arrow. Masochism is mentioned, and the music of…
I have moved this blog from distill over to quarto, and taken notes. A year after starting the blog, this promises to be an interesting reproducibility test
Somehow I was convinced that using Amazon S3 would be a supremely difficult thing to learn, kind of like learning git and GitHub for the first time. Thankfully, it’s…
A post describing fundamental data types in R and Apache Arrow, and how data is exchanged between the two systems. It covers conversion of logicals, integers, floats…
Social media safety tools like muting and blocking are often misused, but for people who are targeted for harassment they are powerful and important. This is a brief…
I’ve been learning how to program with Apache Arrow inside R, and also I have been watching the SyFy show “The Magicians” obsessively. For no sensible reason I wrote a blog…
A quick post on how to use RStudio public package manager instead of a standard CRAN mirror, and an example of why that can be useful sometimes.
I’ve been wanting to learn the basics of Apache Arrow a while: this is the story of how an R user learned to stop worrying and love a standardised in-memory columnar data…
A terrifying descent into madness, or, an explanation of how R serialises an in-memory data structure to summon a sequence of bytes that can be saved or transmitted.…
An example showing how to build a generative art system in R. The post walks through some of the creative and design choices that are involved, and highlights how much of a…
An extremely incomplete (and probably biased) list of resources to help an aspiring generative artist get started making pretty pictures in R
Not every artist wants to make cryptoart, and that’s okay. Others do, and that’s okay too. But if you want to try it out in a socially responsible way, it takes a bit of…
A gentle walkthrough of a few data wrangling and visualisation tools using the Billboard 100 data for this weeks Tidy Tuesday. Pitched at beginners looking to refresh their…
An essay and tutorial covering a few useful art techniques in R
A sick sad story in which a humble R user was forced to learn something about how linux stores passwords and, more importantly, got R to use her GitHub credentials properly
Comments on an exhibit I contributed to as part of useR!2021
How to enable bootstrap 4 on a distill website, even though you probably don’t need to. I like it though because I get to add pretty bootstrap cards
How to make a gorgeous command line interface in R using the cli package. Somewhere along the way I accidentally learned about ANSI control codes, which strikes me as…
I have reluctantly decided to create a new blog. Some thoughts on what I hope to achieve, having tried my hand at blogging so very many times before
