class: center, middle, inverse, title-slide # Final comments ### Abhijit Dasgupta, PhD ### Spring 2019 --- layout: true <div class="my-header"> <span>BIOF 439, Spring 2019</span></div> --- ## Final Projects The final projects are generally great, and some of you have done a fantastic job. I've learned about nuances of ggplot from these project I didn't know before 😄 --- ## Some pitfalls - R Markdown documents are meant to be reproducible, so are self-contained - Put all the `library` commands you need inside the document. On knitting, a new R session is started, so you have to be explicit in packages - Same goes for data imports - Many of you put full paths to data sets in your documents. Those won't be the right paths on my computer 🙀 - The `here` package is your friend - Read [this presentation](https://speakerdeck.com/jennybc/zen-and-the-art-of-workflow-maintenance) by Jenny Bryan for a lot of good ideas about workflow maintenance - For that matter, read [anything](https://speakerdeck.com/jennybc/) by Jenny Bryan. Her work is something I always turn to for practical issues and best practices in R --- ## Next steps - Presentations by Hadley Wickham, Jenny Bryan, Jared Lander, Daniel Chen - The R4DS book - Look on [bookdown.org](https://bookdown.org) for other free R books - One of the better ones for you guys is [Modern Statistics for Modern Biology](http://web.stanford.edu/class/bios221/book/) by Susan Holmes and Wolfgang Huber at Stanford - Videos of presentations (and often materials) at rstudio::conf, New York R conference, DC R Conference, satRdays, EARL, Bioconductor and R-Ladies.
