General info

We’re a bi-weekly open coding café for anyone working at Steno Aarhus (SDCA), Dept. of Endocrinology (HoK), AU-Public Health, AU-Clinical Medicine and AU-Biomedicine to come and get help with their code.


Format

Below are the planned dates; you can arrive and leave at any time.

There will be a ~15 minute presentation at the beginning of each session, tackling a relevant topic (a general R concept, workflows, helpful packages, etc.)

Subsequently, 1-2 experienced instructors will help with your specific challenges and questions. But please interact with each other—maybe someone in the group has the solution to your exact problem.

You’re expected to have an introductory knowledge of R and RStudio; consider
