R in latex R in latex Presentation Transcript

  • Mix source code and documentation together A Write R code in LTEX using knitr, xtable and RStudio Julyan Arbel CREST-INSEE, Universit´ Paris-Dauphine e February 28, 2013Julyan Arbel (CREST-INSEE) R code in L EX AT February 28, 2013 1 / 10
  • GoalTo have a single document which includes source code for easy update. A Use a single software: R interfaces LTEX, as it does with C++, JAGS, (Word, Excel?), etc. Julyan Arbel (CREST-INSEE) R code in L EX AT February 28, 2013 2 / 10
  • First things We will use the knitr package which allows you to embed R code and figures A in LTEX documents (it is an evolution of Sweave). See the package homepage http://yihui.name/knitr/ A You need a valid LTEX distribution We will use knitr in RStudio, because it’s well integrated in itinstall.packages("knitr")library("knitr") Julyan Arbel (CREST-INSEE) R code in L EX AT February 28, 2013 3 / 10
  • Write a first document Open a new ”R Sweave” document in RStudio You can check that the toolbar now includes Format and Compile PDF buttonsdocumentclass{article}begin{document}end{document} Write your text, and insert code chunks [Ctrl+Alt+I] for graphs or tables. A code chunk consists in R code inside the following lines (mind to write both on single lines, with no comment) <<>>= @ code values in the text with Compile [Ctrl+Shift+I] Julyan Arbel (CREST-INSEE) R code in L EX AT February 28, 2013 4 / 10
  • What to put in code chunksAny code that you want to evaluate / not to evaluate, or show / hide: you caneither show the code, or its result, or both. Functions Graphs Tables Global options Set working directory, etc. Julyan Arbel (CREST-INSEE) R code in L EX AT February 28, 2013 5 / 10
