Want to build AI Bots with R? Combining the {ellmer} package with the Shiny framework might be exactly what you need. And I'm happy to share that I get to talk about how that works at this year's ShinyConf 🎉 If you want to join, you can still sign up at www.shinyconf.com/agenda #rstats

Ever wanted to restrict your Quarto project to only a few select people? You can do so by 1️⃣ Hosting your project on Azure Static Web Apps 2️⃣ Creating your own user base via Azure's AAD B2C service 3️⃣ Configuring your app so that it only allows users from your user base #rstats (1/2)

The nice thing about hosting a Quarto project on Azure is that you can easily enable social logins via vendors like GitHub, Apple or Google. All you have to do is 1️⃣ Add an "auth" section to your config file 2️⃣ Get a client from the identity provider (e.g. Google) (1/3) #rstats #datascience

I used to think that securing a Quarto website is about writing lots of code. But really it only requires ✅ hosting on Azure static web apps, ✅ creating a JSON file inside of your Quarto project, and ✅ filling that file with values that you can look up in the docs. #rstats #datascience (1/2)

Hosting Quarto projects on Azure is an easy way to add user authentication to your project. That way, only selected users can access your web page. All you need for that is 🔹 a GitHub repo, 🔹 an Azure subscription, and 🔹 Azure's static web apps service.

It's fascinating how easy text analysis has become in recent years. Nowadays, text analysis reduces to 1️⃣ feeding a document/image to an OCR service like Textract, and 2️⃣ sticking the results into an LLM. No huge entry barriers for data scientists to dive into text processing. #rstats #datascience

New chapter for the "AI With R" book 🥳 We're getting started with the {ellmer} package. This package has lots of features like ✅ tool calling to mix AI with traditional functions, ✅ structured output to extract infos, and ✅ async streams to build chat bots. #rstats #AI #datascience

But what if you have a PDF? In that case, you can use the pdf_convert() function from the {pdftools} package to make the PDF into an image. Then, you can use the previous steps. That's it. Not really much you have to do.

Let's imagine you have an image of an invoice. You can put that into one of {ellmer}'s content objects. Key function here is content_image_file()

With AI, it's really easy to process invoices or other documents using R. Here's what you have to do: #rstats #AI

New Project: AI With R 🥳 I've been writing about how to use AI/LLMs with R. So I'm happy to share that I'm starting to collect all the materials in one central space. You can read the first two chapters at buff.ly/3PQNzWz #rstats #AI

Check out this AI chat-bot I built with #rstats using {elmer} and {shiny} 🥳 The crucial steps are 1️⃣ Insert textboxes with insertUI() 2️⃣ Stream LLM responses into the textboxes Want more details? Tomorrow, I show 3200+ readers how I built this thing. You can join us at 3mw.albert-rapp.de/subscribe

My solution to today's #adventofcode in #rstats. Took me a while to realize that I can get reverse diagonals by just using diag() on the matrix with column indices chosen descendingly 😅

Glad to see that the #rstats community is sharing their #AdventOfCode solutions. Here's mine. For some reason it was a pain to get the regex for Part 2 right so I just brute-forced it (find indices between all don't and dos and then remove those chars) 🤣 btw is there an R leaderboard this year? 🤔

Look at this fantastic diamond chart 🤩 You can create such a beauty with ggplot using one simple trick: 1️ Use a regular grid and plot all texts at a 45 degree angle 2️⃣ Turn the whole chart counter-clockwise Pretty dope trick that I've learned from a tutorial on the F5 Newsletter. (1/2) #Rstats
