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/ "https://lib.dr.iastate.edu/etd/13518/") was _Dynamic [Graphics](https://github.com/ggobi/cranvas "https://github.com/ggobi/cranvas") and [Reporting](/knitr/ "https://yihui.org/knitr/") for Statistics_, advised by [Di Cook](https://www.dicook.org "https://www.dicook.org/") and [Heike Hofmann](https://www.stat.iastate.edu/people/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 "https://cran.rstudio.com/package=fun") (or both), such as [litedown](/litedown/ "https://yihui.org/litedown/"), [knitr](/knitr/ "https://yihui.org/knitr/"), [animation](/animation/ "https://yihui.org/animation/"), [bookdown](https://bookdown.org "https://bookdown.org/"), [blogdown](https://github.com/rstudio/blogdown "https://github.com/rstudio/blogdown"), [pagedown](https://github.com/rstudio/pagedown "https://github.com/rstudio/pagedown"), [xaringan](https://slides.yihui.org/xaringan/ "https://slides.yihui.org/xaringan/"), and [tinytex](/tinytex/ "https://yihui.org/tinytex/"). I founded a Chinese website called “[Capital of Statistics](https://cosx.org "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 "https://github.com/yihui"), [LyX](https://www.lyx.org "https://www.lyx.org/") and [Pandoc](https://pandoc.org "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 "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。
