Straight from my sticky note, three functions that I like a lot, despite their not being new at all… But maybe new to some of you? sprintf(), the dependency-free but less neat “glue” Imagine I want to tell you who I am. I could write... [Read more...]

My sticky note is full! And luckily all functions on it can be squeezed into a similar topic: making things smaller! Make lists smaller with purrr::compact(), purrr::keep(), purrr::discard() Once upon a time there was a list (isn’t this the begin... [Read more...]

There are already three functions of note on a piece of paper on my desk, so it’s time to blog about them! How does this package depend on this other package? pak::pkg_deps_explain() The pak package by Gábor Csárdi makes installing packages easie... [Read more...]

I (only! but luckily!) recently got introduced to the magic of purrr::reduce(). Thank you, Tobias! I was told about it right as I was unhappily using many for loops in a package1, for lack of a better idea. In this post I’ll explain how purrr::re... [Read more...]

Following my recent post on three useful (to me) R patterns, I’ve written down three other things on a tiny sticky note. This post will allow me to throw away this beaten down sticky note, and maybe to show you one element you didn’t know? ... [Read more...]

I’m happy to report that I thought “oh but I know a better way to write that code!” a few times lately when reading old scripts of mine, or scripts by others. It’s a good feeling because it shows progress! I’ve tooted abou... [Read more...]

If you’ve been taught git and GitHub but practice so rarely that you’re discouraged, what should you do to re-start more easily? Let’s imagine you have to, or really want to, use git and GitHub for your next analysis project. Here&rsq... [Read more...]

I found an excuse to blog about XML again! Yes, RSS feeds are in practice XML, but for most people, that’s not why they are cool. An RSS (really simple syndication) feed is metadata about all, or the most recent posts published by a website: publ... [Read more...]

One of my favorite tool is XPath, the query language for exploring XML and HTML trees. In this post, I will highlight a few use cases of this “angle-bracket crunching tool” and hope to convince you that it’s an awesome thing to know about and play with. Many thanks ... [Read more...]

I’m spending quite a lot of my working time on GitHub, so have taken some habits. Maybe some of them can be useful to you! 1: How to get started I’ve never actually taught git and GitHub, but I like sharing these useful links: [Happy Git ... [Read more...]

Huge thanks to Hannah Frick for her useful feedback on this post! Vielen Dank! When trying to fix a bug or add a feature to an R package, how do you go from viewing the code as a big messy ball of wool, to a logical diagram that you can ... [Read more...]

I’ll be giving a remote keynote talk at the Rencontres R (French R conference) on July the 12th, all in French. This blog post is a written version of my presentation, but in English. I decided to not talk about package development for once, but ... [Read more...]

Whilst I most certainly do not write LaTeX formulas on the regular anymore, I got curious about their MathJax rendering on websites.1 In brief : your website source contains LaTeX code, and the MathJax JS library (self-hosted or hosted on a CDN) transf... [Read more...]

I’ve just finished teaching blogging with R Markdown at R-Ladies Bangalore. This has two consequences: I need to calm down a bit after the stress of live demoing & co, and I am inspired to, well, blog with R Markdown! As I’ve just read ... [Read more...]

My kids got a cool electronic storyteller as a gift. It is basically a pretty cube that you shake to make it play tracks. La conteuse merveilleuse comes with pre-loaded songs and stories, but you can also add your own. Very handy, as we had e.g. CDs th... [Read more...]

A big part of my work includes putting content about R online, in blog posts and online books. I’m therefore very interested in the technical infrastructure that allows us R users to produce beautiful products out of R Markdown or Markdown source files. In this post I shall summarize ... [Read more...]

Last week I had the pleasure to lead an online course about “Scientific Blogging with R Markdown”, invited by Najko Jahn and Anne Hobert from SUB Göttingen. To follow the example set by the incredible Alison Hill, I’ll write a summary of what I’ve learnt and would ... [Read more...]

I’ve recently found myself having to write a bit of CSS or JS for websites made with Hugo. Note for usual readers: it is a topic not directly related to R, but you might have played with either or both CSS and JS for your R blog or Shiny ... [Read more...]

Fancy (re-)creating your website using Hugo, with or without blogdown? Feeling a bit anxious? This post is aimed at being the Hugo equivalent of “What to know before you adopt a pet”. We shall go through things that can/will break in the future, and what you can do ... [Read more...]
