Yihui’s TODO List

This page contains some of my TODO items. I guess I will never be able to finish all the work, so I will appreciate your help with any of the items on this page (fixing bugs, answering questions, or implementing features). Please feel free to let me know if you want to work on anything, and I will be happy to assist you.

Looking at these items, you may make a better decision on whether to ask questions on a public forum before emailing me, according to my current status below. Please feel free to email me anyway if you do not need a prompt response, and please forgive my slow response.

Status

At the moment, I have 92 emails in my inbox to be dealt with (the earliest that I have not replied to was from Nov 21, 2018), 0 unread GitHub issues/PRs, and about 40 tabs open in my browser.

Help Needed

If anyone is interested in any of the items below, please feel free to let me know. I’d be happy to explain more, or do a video chat with you.

1. Land the xaringan slide page in RStudio Viewer corresponding to the cursor position in RStudio IDE: https://github.com/yihui/xaringan/issues/336
2. How can users build and install their own version of TinyTeX? Short answer: install TinyTeX-0, use tlmgr to install the packages they need, zip the TinyTeX installation directory, and publish it somewhere (e.g., GitHub Releases, or AppVeyor artifacts). To install this custom version of TinyTeX, I’ll need to provide an environment variable to customize the URL in my installation scripts (e.g., not hard-coding yihui.org or github.com/yihui/tinytex-releases in install-bin-unix.sh), so they can be reused by others.
3. Introduce the easier way to start a bookdown project using the RStudio IDE in the book: https://github.com/rstudio/bookdown/issues/225
4. Build rggobi on r-universe.dev: https://github.com/ggobi/rggobi/issues/7
5. More accessibility/navigation tags in knitr::kable_html(): https://github.com/yihui/knitr/issues/1747
6. Generate the Table of Contents for xaringan slides: https://github.com/yihui/xaringan/issues/217
7. How to render math expressions without MathJax? https://stackoverflow.com/q/57121846/559676 Alternative methods are listed here: https://pandoc.org/MANUAL.html#math-rendering-in-html
8. The pain of using rmarkdown on network drives: https://github.com/rstudio/rmarkdown/issues/1268
9. BibTeX references showing up twice in bookdown: https://github.com/rstudio/bookdown/issues/751
10. Make TinyTeX more portable: https://github.com/yihui/tinytex/issues/133
11. xfun::numbers_to_words() for numbers with decimal places: https://github.com/yihui/xfun/issues/18
12. Live code in xaringan: https://github.com/yihui/xaringan/issues/206 The implementation is not totally clear to me, but I imagine users can double click on a code block on a slide to edit the code, and the edit can be sent back to the RStudio IDE or executed.
13. https://github.com/rstudio/pagedown/issues/236 chrome_print() stops working after a few hundred times
