Since I have been asked several times how I created my slides, I’m going to share a little secret about my slides in this short post: most of my slides in the recent years were generated from R Markdown,1 and you can easily obtain the .Rmd source documents if you replace the extension .html with .Rmd in the address bar of your web browser. That’s it. For example, for the slides at
https://slides.yihui.org/2018-blogdown-rstudio-conf-Yihui-Xie.html
The Rmd source file can be obtained from:
https://slides.yihui.org/2018-blogdown-rstudio-conf-Yihui-Xie.Rmd
I host most of my slides in my Dropbox folder and serve them through Updog,2 so I don’t need to explicitly upload them to a server, and you have access to any files in this folder.

When sending money, please be sure to add a note “gift” or “donation” if possible, so it won’t be treated as my taxable income but a genuine gift. Needless to say, donation is completely voluntary and I appreciate any amount you can give.
Please feel free to email me if you prefer a different way to give. Thank you very much!
I’ll give back a significant portion of the donations to the open-source community and charities. For the record, I received about $30,000 in total (before tax) in 2024-25, and gave back about $15,000 (after tax).
