We've released our videos of the talks at the 2018 RStudio conference. My talk was Modeling in the Tidyverse (video) and I was also in the Tidyverse fireside chat (video). There are a lot of great talks on the conference website.
I also conducted a two day workshop on caret and the new modeling packages (recipes, rsample, tidyposterior and others) at the conference. The was no video of that, but all of the materials can be found in the course GitHub repository.
There will be at least one other workshop for this year on these topics. When that is finalized, I'll post the details here and on on twitter.
