we are getting close to conference season, so I put together some of my slidecrafting material: it is quite bare bones at the moment, but I will fill in and add more stuff as I start slidecrafting myself

A fantastic day at #satRdays London conference today!

My slides on "Typst or LaTeX? Styling PDF documents with Quarto extensions" are available online 👀

emilhvitfeldt,

@nrennie @jumpingrivers I love these slides! the "About Me" slide is magical ✨

As part of the tidymodels team, I'm excited to share with you our next project survey. Beside our planned work on postprocessing and supervised feature selection, we would love to hear what the community would find interesting and useful!

I'm at a good spot with the section on "Missing Data" in my new book "Feature Engineering A-Z". Please take a look, would love the feedback 🙏

I'm beyond excited to finally announce my new book "Feature Engineering A-Z" 🎉

The vision for the book is to be a comprehensive collection of feature engineering methods. Describing how they work, when and why you should and shouldn't use it. Code snippets in both R and Python!

I have been working on this project over the last couple of years. Please read it if this interests you! Always looking for feedback!

I was going to do my corp mandated internet security training. Only it needs popups. <sigh> ... I wonder if it needs cross site scripting and third party cookies too?

emilhvitfeldt,

@Cmastication WAIT! we have to read our email?!

For those of you that have followed along with #adventofsteps, I have now put all the material on Github, and you can see the slides that I used to create the images for each day

For day 24 of #adventofsteps we look at a fun alternative to dummy variables

Feature hashing is an interesting technique where you create dummy variables, but instead of giving each level its own column, you run the level through a hashing function to determine the column. This means that any number of levels can be put into a fixed number of columns

All the #PositConf2023 talks are now on Youtube 🎉

They are all great, and if you missed mine you can find it with the following link! Also linked are slides and source code

Wrote a short blogpost on different ways and websites that you can use to post pictures of code on social media

Kicking off #adventofsteps where I show you a {recipes} step I hope you will find useful each and every days for 25 days!

First step we will look at is step_dummy_extract(), this steps pulls out all the levels in a string and counts them like step_dummy() would

With sep or pattern and a bit of regex you can handle any kind of data

Gave a talk for the lovely people of The R User Group at the Harvard Data Science Initiative yesterday on "what's new in tidymodels"

I'm back with new and improved color palette discovery with https://emilhvitfeldt.github.io/r-color-palettes/!

Find the perfect palette from {paletteer} with a few clicks. see it in use and find other palettes that look just like it!

I resisted for too long. I’m on the RSS train! Happy to hear any tips and favorites

emilhvitfeldt,

@joel I watched 1 YouTube video and they used feedly, so so am I 😅

Gosh I hope folks in abuse situations had their phones off. All my stuff was on silent and it still was super loud.

emilhvitfeldt,

@hrbrmstr SUPER LOUD

Slides and source for my #PositConf2023 talk "Styling and Templating Quarto Documents" AKA "worried about styling taking too much time? In 20 minutes you won’t anymore" It was an honor to talk and speak with so many wonderful people!

Day 1 of #positconf2023 🎉
Intro to tidymodels is running smoothly so far!

Just got my first start-to-finish at-least-all-the-slides-are-there deck for my #PositConf2023 talk next week! Fondly remembering naive me who thought the slidecrafting would only take infinity ♾️

emilhvitfeldt,

@Cmastication @grrrck don't worry! there is plenty of time! I haven't started on my last slide deck yet...

emilhvitfeldt,

@grrrck @Cmastication just add Reveal.shuffle() to a sample of past slides and we are rolling

I just discovered that quarto slides have a "shuffle" mode and now I'm contemplating presenting at posit conf in chaos mode

emilhvitfeldt,

@grrrck The trick is to have it turn on sometimes! By adding this to your quarto document

&lt;script&gt;  
 window.addEventListener("ready", function() {  
 if (Math.random() &gt; 0.1) {  
 Reveal.shuffle()  
 };  
 });  
&lt;/script&gt;

I did it again! wrote another #quarto extension, this time a Revealjs plugin to spruce up code blocks!

Make code blocks look like browser windows, complete will file names and ICONS! many data science icons are already enabled

We are ready with another set of release for {recipes} and the extension packages {textrecipes}, {themis}, and {embed} 🎉

While it isn't reflected in the NEWS files, a lot of work was done over the last couple of months. The work was focused on internal refactoring, improving test coverage, and increased consistency.

With these changes done, I expect many great things in the future!

https://github.com/tidymodels/recipes/releases/tag/v1.0.7
https://github.com/tidymodels/textrecipes/releases/tag/v1.0.4
https://github.com/tidymodels/embed/releases/tag/v1.1.2
https://github.com/tidymodels/themis/releases/tag/v1.0.2

<rant> #rstats packages should run single threaded by default </rant>

emilhvitfeldt,

@ERDonnachie I'm not in a finger pointing kinda mood, but there are lots of packages that default to all cores, or all - 1 cores
