29 September 2022, 5-6 PM ET — Level Up Your Plots

Polished annotations can make all the difference between a good plot that contains all the necessary information, and a great plot that engages readers with a clear story.

This talk will build on the Introduction to ggplot session, exploring how we can make good use of design tips (and the coding tricks behind!) to help readers understand the key messages that our datavisualisations seek to convey. We will build an annotated plot step by step and discuss why we're doing things the way we are along the way.

By the end of the session, you'll have a clear grasp of how to:

  • use colour in the explanatory text as well as in the plot to help the readers orient themselves
  • use primary and secondary text colours and fonts to help the main message stand out
  • create labels to add information about specific data points
  • add arrows and use text alignments to draw attention to important details
  • modify the theme and other parameters to give everything some space to breathe
Attendees are encouraged to submit one of their plots in advance of the session if they would like to get some feedback on their plot design and annotations.


Past Events

21 October 2021 — Intro to {dplyr} and USAFacts COVID-19 Data

Join us for an introductory talk on how you can use {dplyr} to transform and analyze data. We will introduce the principles behind the tidyverse and teach you how to create new variables, transform existing ones, tidy data from a wide format to a long format (or vice versa), and more.

18 November 2021 — Cooking Your Data with Recipes

Recipes are tools for preprocessing data prior to modeling or visualization. You can think of them as a mash-up between `model.matrix()` and dplyr. We'll walk through some recipes and how they can be used with models or visualizations that use dimension reduction.

19 March 2022 — Creating Interactive Tutorials with {learnr} by Yanina Bellini Saibene

The {learnr} package makes it easy to turn any R Markdown document into an interactive tutorial. Tutorials consist of content along with interactive components for checking and reinforcing understanding. Tutorials automatically preserve work done within them, so if a user works on a few exercises or questions and returns to the tutorial later they can pick up right where they left off. Learn more about {learnr} here.

10 March 2022 — Creating features for machine learning from text

Julia Silge is a software engineer at RStudio PBC where she works on open source modeling tools. She holds a PhD in astrophysics and has worked as a data scientist in tech and the nonprofit sector, as well as a technical advisory committee member for the US Bureau of Labor Statistics. She is an author, an international keynote speaker, and a real-world practitioner focusing on data analysis and machine learning. Julia loves text analysis, making beautiful charts, and communicating about technical topics with diverse audiences.

Natural language that we as speakers and writers use must be dramatically transformed to new representations for analysis, whether we are just starting off with exploratory data analysis or are ready to train machine learning algorithms such as predictive models. We can explore typical text preprocessing steps from the ground up, from tokenization to building word embeddings, and consider the effects of these steps. When are these preprocessing steps helpful, and when are they not? In this talk, learn about the process of text preprocessing for ML models in the real world, how and when practitioners use different preprocessing choices, and considerations for text ML tooling.

30 June 2022 — Celebrating our 1 Year AnniversRy

Come join us to celebrate our one year anniversRy! Mingle with fellow R users, learn about opportunities to engage with the R community, share your favorite recent R related events, and get excited for the return of jeopaRdy!!

20 January 2022 — Organizer Interest Meeting

Are you interested in helping us make our R User Group better? Join our Organizer Interest Meeting! We will have free time to discuss what you'd like to see us do with the organization, suggest guest speakers, and volunteer yourself to help us organize our R User Group.

17 February 2022 — R you my Valentine?

Join us to share tips and tricks that make you *love* R!

02 December 2021 — Introduction to ggplot2

Do you want to take your data visualization skills to the next level? Come to our talk on ggplot2, a package in R that uses the grammar of graphics system to make it easy to create everything from simple and stunning to complex and sophisticated plots.

Our talk will cover three ways to use ggplot2:

  1. the basic ways you can use ggplot2 to create simple data visualizations,
  2. the extensions to ggplot2 that you should know about and help you quickly create more advanced data visualizations, and
  3. how you can create functions that use ggplot2 to help you automate creating data visualizations.
Our talk is intended to provide you the resources and know-how to create data visualizations that accelerate your research, knowledge discovery, and the communication of your findings.

05 August 2022 — {plumber}: An API Generator for R

{plumber} is an R package that allows users to create web APIs by decorating R functions using {roxygen2}-like comments. In this meetup, we will go over the basics of an API, a server, and how plumber can help you create a web-based API using R so that you can share your data/research/visualizations/{htmlwidgets} to the world.

19 August 2021 — R Trivia & Happy Hour

Join us for a virtual happy hour and mingle with other R users!

18 August 2022 — Intro to Git and GitHub with R and RStudio

Join us to learn about how to use the Git software to version control your code and much more. Version control software, like Git, is like track changes for your code, but even more powerful! Git enables you not just to track the iterations of your codebase, but to easily collaborate with others (without emailing zip files back and forth!), to go back in time to check how your code used to look, to safely test out new ideas, and much more. GitHub is an online service that provides free Git services so you can use it to backup your Git repositories, share them with others – and even build out websites and a professional portfolio of your software and programming work. GitHub is one of the most relevant technologies for any programmer, so we welcome you to join us to learn how you can leverage Git and GitHub for your R programming adventures!

14 July 2021 — BeginneR's Workshop

Join us for an introductory session on using R and RStudio to analyze data and create data visualizations.

22 June 2021 — TidyTuesday Lunch & Learn

We watched a pre-recorded (available on YouTube) talk from Julia Silge on how she analyzed highly ranked hip hop songs using data from the Spotify API and using principal components analysis.

10 June 2021 — First Inaugural RUG Meeting

In our first meeting we learned about who was attending through casual conversations and surveys and what people are looking for from our organization.
