I'm currently a freelancer, and was a software engineer at Posit Software, PBC
(2013-2023). I earned my PhD from the Department of Statistics, Iowa State
University. My [thesis](https://lib.dr.iastate.edu/etd/13518/) was *Dynamic
[Graphics](https://github.com/ggobi/cranvas) and [Reporting](/knitr/) for
Statistics*, advised by [Di Cook](https://www.dicook.org) and [Heike
Hofmann](https://www.stat.iastate.edu/people/heike-hofmann). I have developed a
series of R packages either seriously or for
[fun](https://cran.rstudio.com/package=fun) (or both), such as
[litedown](/litedown/), [knitr](/knitr/), [animation](/animation/),
[bookdown](https://bookdown.org),
[blogdown](https://github.com/rstudio/blogdown),
[pagedown](https://github.com/rstudio/pagedown),
[xaringan](https://slides.yihui.org/xaringan/), and [tinytex](/tinytex/). I
founded a Chinese website called "[Capital of Statistics](https://cosx.org)" in
2006, which has grown into a large online community on statistics. I initiated
the China R conference in 2008. I'm a big fan of
[GitHub](https://github.com/yihui), [LyX](https://www.lyx.org) and
[Pandoc](https://pandoc.org). I used to hate IE but no longer care since it has
almost died. I fall asleep when I see beamer slides, and I yell at people who
use `\textbf{}` to write `\title{}`. I know I cannot eat code, so I cook almost
every day to stay away from my computer for two hours.

这是谢益辉的主页。2013 年底我从 [Ames
村办大学](https://www.iastate.edu)统计系毕业，终于解决了人生前三十年被问最多的问题："你怎么还没毕业？"目前为自由职业者。我支持开源，喜欢折腾网站和代码，是个高度自我驱动的人。打羽毛球爱勾对角，打乒乓球像太极，网球满场子捡球，篮球容易被撞飞，攀岩一次，腿软。宅，口重、嗜辣、屡教不改。智商中等偏下，对麻将和三国杀有不可逾越的认知障碍，实变函数课上曾被老师叫醒。略好读书与文，对诗词楹联感兴趣，目前较中意的一联是：千秋邈矣独留我；百战归来再读书。最喜欢的一首词是：

> 深情似海，问相逢初度，是何年纪？依约而今还记取，不是前生夙世。放学花前，题诗石上，春水园亭里。逢君一笑，人间无此欢喜。  
> 无奈苍狗看云，红羊数劫，惘惘休提起。客气渐多真气少，汩没心灵何已。千古声名，百年担负，事事违初意。心头阁住，儿时那种情味。
