I'm taking the Instructor Training for the Carpentries and it requires a short (90-second) introduction to an episode on one of the Carpentry lessons pages. That introduction (to my mind) must include at least some example code so I'm writing that in this repository.
Additionally, I think there may be some follow-along coding in the training and it could be helpful to have my own repository for that (if one is not already set up for us in advance).

The lesson I selected to teach a short intro on was "Data Analysis and Visualization in R for Ecologists". The lesson's GitHub repository is linked here
