Join us for a relaxed evening with tea, snacks, and good company. Bring an R challenge you've been stuck on, a project you want to make progress on, or just yourself. There's no agenda, no slides -- just a room full of people who like R (and snacks). Whether you're a beginner looking for a nudge in the right direction or a seasoned R-user happy to share what you know, you're welcome here. The event will take place in the room ØHM11. The outer door is locked, but we will wait outside to let you in, or call me on 47641800.

This workshop walks through a complete text analysis pipeline in R, combining traditional methods with newer AI-powered tools. In the first part, we will cover tokenization with tidytext, stopword removal (including custom stopwords), word frequency visualization with wordclouds and bar plots, dictionary-based sentiment analysis using three lexicons (AFINN, Bing, and NRC), topic modeling with LDA, and bigram analysis with word networks. In the second part, we explore how the mall package can be used to perform sentiment analysis with local LLMs (via Ollama), comparing this approach to dictionary-based methods, and look at related tasks like text classification and entity extraction. Familiarity with R and the tidyverse is assumed.

En este taller introductorio vamos a acercarnos a la **Teoría de Respuesta al Ítem (TRI)** de una manera práctica y accesible. La TRI sirve para entender mejor **cómo funcionan los ítems (preguntas) de un test y cómo miden una habilidad o rasgo**. Nos permite ver, por ejemplo, si un ítem es más fácil o más difícil, si discrimina bien entre personas con distinto nivel, y si funciona de manera consistente. También es una herramienta muy útil para seleccionar los mejores ítems, acortar tests sin perder calidad y diseñar escalas más precisas. A lo largo del encuentro, vas a: \- Construir una comprensión conceptual de sus ideas principales\. \- Aplicar este método usando R\. \- Aprender a interpretar sus resultados para entender mejor cómo funcionan los ítems y qué aportan a la medición\. Este taller es **introductorio** y está dirigido a personas con un **conocimiento básico de escalas psicométricas**. **No requiere conocimiento previo de Teoría de Respuesta al Ítem.** **Requerimientos:** * R: 4.5.1 (mínimo) * RStudio: 2025.05.1 (mínimo, descargar [aquí](https://posit.co/downloads/)) * Instalar los paquetes **tidyverse, mirt y ltm**

🔜 We are excited to announce our next virtual meetup in collaboration with R-Ladies Abuja (https://www.meetup.com/rladies-abuja/). Join us on May 13 from 7:00 pm to 8:00 pm CEST (GMT+2) for a talk on performing automatic NLP with LLMs using mall with Edgar Ruiz — Software Engineer at Posit. Talk abstract: We’re all too familiar with the grind of building functional NLP: labeling data, fitting models, and endless tuning. In this talk, we’ll see how mall lets us bypass model training entirely by using LLMs to handle complex multilingual translation, sentiment analysis, and entity extraction row-wise across our data. We’ll explore how to run these solutions using a familiar R syntax, whether you're working with local models for privacy or remote APIs for scale. We look forward to seeing many of you there!

A personal website is a great way to showcase your data science skills, highlight projects, and share what you’re passionate about. In this workshop, we’ll learn to build a personal website using Quarto, an accessible and flexible publishing framework, to help you get started. Together, we’ll: * Build the core components of a Quarto website * Add a blog to share your work and projects * Use Sass to customize colors and fonts * Walk through deploying your website \~for free\~ using GitHub Pages Whether you’re just getting started or looking for a Quarto refresher, this workshop will provide you with the tools you need to share your work with an online audience. If you’d like to follow along during the workshop, please install and configure a few tools ahead of time by working through these [initial setup instructions](https://samanthacsik.github.io/RLadiesSB-quarto-websites/#setup).
