> **fonzie** (@OilGains; 2/0): See my review on Claus Wilke's bookdown on "Fundamentals of Data Visualization". He provides the #rstats souce code. I put it together with the libraries in a Docker container https://t.co/bjV9Kb6Nfm. I am sure the structure will be useful for you. https://t.co/9DUVkR6rOM  [&#8618;](https://twitter.com/xieyihui/status/1040478064700940289)

# knitr

The most awesome/useful discovery has been ✨ knitr::opts_chunk$set(error = TRUE)  ✨ for including error messages in Rmd.

Super useful to be able to show when and why code might fail!  [&#8618;](https://twitter.com/xieyihui/status/1040605885050040321)
