Já tentou construir um gráfico no R usando o pacote ggplot2 e teve a sensação de que estava aprendendo outra língua? Pois é: o ggplot2 tem uma lógica própria. A boa notícia é que, depois de entendê-la, dificilmente você vai querer voltar a montar gráficos manualmente no Excel. Neste minicurso, vamos explorar os princípios fundamentais do ggplot2, partindo do zero até recursos mais avançados de personalização, para que você consiga construir gráficos elegantes, informativos e reproduzíveis no R.

We are pleased to welcome **Eva Flonner** from UNIQA Insurance Group to present an R package for health insurance. Join us to explore how R can be put to work in actuarial practice, from data to modeling to simulation. As we promote gender diversity and inclusion in the R community, all genders and skill levels in R are welcome! **ℹ️ Abstract** **HePriceR** is an R package for health insurance pricing that provides a framework for modeling expected claims and their uncertainty. The package consolidates classical actuarial approaches with modern statistical modeling, enabling transparent, reproducible, and extensible actuarial workflows. The core focus of HePriceR lies in the estimation of expected claims and their uncertainty. It implements multiple methodological approaches, including the Rusam method for expected claims, as well as comprehensive frequency–severity modeling. The package further provides technical implementations for common product design features, such as deductibles, sublimits, and benefit caps, ensuring that modeled claim distributions align with contractual reality. From a software design perspective, HePriceR relies on a structured system of S3 classes and methods, including dedicated hpr_pricing_data objects and corresponding fit objects. This design enables consistent handling of data, fitted models, diagnostics, and downstream simulation. On top of the fitted models, the package offers Monte Carlo simulation capabilities. Overall, HePriceR provides a cohesive actuarial toolkit that bridges actuarial methodology and statistical modeling, supporting both daily operations and advanced analytical use cases. This package is based on joint work with Herr Kompott. **🗺️ Location** TU Wien Freihaus Wiedner Hauptstraße 8-10, 1040 Vienna ([map](https://maps.app.goo.gl/N8PSCZfdi97KirFY6)) Exact room to be announced soon.

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. Mazemap: https://link.mazemap.com/E1NxhvoO Google maps: https://maps.app.goo.gl/MbuZZPL8m2simBwd9 The room may be a bit confusing to find, because it is NOT in the main building of Øya helsehus, it is in a smaller building right east of it.

Are you an R and/or Python user interested in learning about the [Positron IDE](https://positron.posit.co/)? Join the R-Ladies Corvallis community for a workshop led by Posit's very own Charlotte Wickham! You do not need to have any experience with Positron to attend. We'll have snacks and time set aside for mingling and asking questions. We hope you join us! **Workshop details** Positron is the new IDE from Posit — the team behind RStudio. If you've been curious but haven't had the time to try it yet, this workshop is for you. In one hour, we'll get you up and running, with plenty of time to explore and get your questions answered. I (Charlotte) will have a few slides prepared with: * the most important things to know when you are a new Positron user, * tips for transitioning from RStudio, and * Positron features I think make the transition worth it. I'll try to limit how much time I'm talking to give you as much time as possible to actually use Positron and ask questions about it. **Before the workshop** 1. **Check your R version**: Positron requires R 4.2 or greater. To check: open R, and examine the welcome message or run \`R.version$version.string\`. To update: visit [https://cloud.r-project.org](https://cloud.r-project.org) 2. **Install Positron**: [https://positron.posit.co/install.html](https://positron.posit.co/install.html)
