R-Bar is a weekly scientific programming study group where we tackle R issues in a cooperative group setting. This initiative is now happening at various universities in Atlantic Canada; this page represented the RBar group at Memorial University in Newfoundland, Canada.

RBar at Memorial University

RBar is a weekly scientific programming study group where we tackle R issues in a cooperative group setting. We welcome people from all disciplines, across all experience and skill levels, including undergraduates, graduates, faculty, and researchers!

Do you have a suggestion for a future event? Would you like to host a tutorial, workshop, or demonstration? Are you willing to share a piece of code that you think might be useful to others, or a solution to a common problem? Let us know! Follow us on Twitter @RBarMUN and/or join our Slack group!

This event is all about sharing the tips and tricks you find most useful, demonstrating the interesting things R can do, and learning from each other!

Introduction to Linear Mixed Effect Models in R

November 25, 2019
Location: The Breezeway, 5:30 - 6:00
Instructor: Sara Sauvé
Target Audience: Intermediate
Suggested Prerequisites: Basic R / RStudio

Linear mixed models are an extension of simple linear models to allow both fixed and random effects, and are particularly used when there is non independence in the data, such as arises from a hierarchical structure. This is a technique commonly used in ecology and across disciplines, so take this fantastic opportunity to skill-up! Tutorial materials can be found here.
