Online sessions

Given that all sessions are online, they need to be as interactive as possible. My role as instructor is to introduce you new tools and techniques, but it is up to you to take them and make use of them. It is best if you can start applying what you learn in the workshop on your own data.


You will also complete tutorials in R for each session.

You need to use RStudio Cloud for all lab sessions.

Please click on this link to connect to RStudio Cloud workspace.

We will also share a link with you on the day through the Slack.
