Sweave is a system for combining S (or R) code with LaTeX in a single document.

Sweave is a system for combining (or ) code with in a single document. It is an implementation of Donald Knuth's concept. For new projects, consider using instead, which is faster and provides more flexibility.

The Sweave file contains normal LaTeX code with R code chunks in it using the following syntax:

<<option1=TRUE,option2=3>>=
R code here
@

Generating a pdf from a Sweave file (generally with a .Rnw extension in R) is a two stage process:

  1. Running Sweave on the Rnw file, which evaluates the code chunks and generates a tex file.
  2. Compile the resulting tex file using e.g. pdflatex.

Sweave offers easy integration of R code into any LaTeX document and makes easier.
