Changing just a tiny little bit in my LaTeX tabular

via

Why struggle with something not essential?

• LaTeX is only one possible authoring tools
• to be clear, I love LaTeX, but it is not for everybody
• see my blog posts here and here later
• 

Two components of a research report (or homework, paper, book, …)

1. the authoring tool
2. the computing tool

One possible combination

1. Markdown
2. R

But we do not copy and paste results

• integrate code into documents
• the value of π is `r pi` instead of 3.14

Automate, automate, automate

knitr

• narrative + code = report
• http://yihui.name/knitr
• forthcoming: Dynamic Documents with R and knitr (Chapman & Hall)

RPubs

• http://rpubs.com
• this is how you/your students should turn in homework
• authoring: die, Word, die!!
• computing: die, Excel, die!!

The Analysis of Data

• http://theanalysisofdata.com/

Why the web?

• easier to write content
• no page limit
• better display of code (think straight quotes and middle tilde in verbatim)
• interactivity

Demo

• local documents
• web documents: http://glimmer.rstudio.com/yihui/knitr

A Github/Markdown-based Journal?

• http://vis.supstat.com

Final words

• I also worked hard on integrating LaTeX with R, but I only introduced R Markdown in this talk
• reproducible research should be easy enough to get started
• enjoy the web
