> **JD Long** (@CMastication; 73/5): I'm teaching an intro to #rstats and #Tidyverse at a client site next week. Seems like the appropriate time to try out {Xaringan}. Going through the docs I realize that I may just have to turn on yolo mode. Open source software totally brings the lols. https://t.co/23lkfc7GSN  [&#8618;](https://twitter.com/xieyihui/status/1192538987556151296)

> **JD Long** (@CMastication; 6/0): so @Emil_Hvitfeldt pointed out that this is specific to {Xaringan} so it probably has something to do with the css libraries at play. Could be useful if your presentation needs to be mirrored for rear projection or some such.  [&#8618;](https://twitter.com/xieyihui/status/1193264611463716865)

> **Miles McBain** (@MilesMcBain; 5/0): @metasdl @lingtax You can knit an Rmd directly to slides ioslides_presentation() works better than {xaringan} for interactive stuff.

> **Andrew Heiss, PhD** (@andrewheiss; 2/0): @edrubin @causalinf Your course materials are srsly the best I’ve come across for intro econometrics, and I might embrace your xaringan-for-problem-sets approach instead of constantly fighting with latex  [&#8618;](https://twitter.com/xieyihui/status/1194070194915811328)

> **Malcolm '🦃 of Courage' Barrett** (@malco_barrett; 2/0): @ustcer_ztc @zhiiiyang I've been following that! I think it's a very sensible solution. I haven't PR'd this one, despite using it for a long time, because I'm still making tweaks and didn't want to have to keep it in sync with a hard coded version in xaringan. But it's nice to make it available  [&#8618;](https://twitter.com/xieyihui/status/1193928910922104832)
