(This article was first published on

**Blog - Applied Predictive Modeling**, and kindly contributed to R-bloggers)- My talk went well; here are the slides and a link to the paper pre-print.
- Hadley Wickham gave an excellent tutorial on
`dplyr`

. - Based on the talk I saw, I think I will take the data sets from the book and make some public visualizations on the
`Plotly`

website. - There were a few presentations on interactive graphics that were very good (here, here and here).
- Tal Galili gave an excellent talk on visualizing and analyzing hierarchical clustering algorithms. (slides)
- The HeR session was great. I also learned about R-ladies.
- Revolution Analytics and RStudio proposed two similar techniques for preserving versions for better reproducibility.
- The subsemble package by Erin LeDell was impressive.
- I had dinner with John Chambers, which was pretty cool too.
