decumar

Decumar is a tool for interleaving latex and R. It uses specially formatted comment blocks, so your file is always valid latex.

Decumar is similar to sweave, but comes from a slightly different heritage. As well as deriving inspiration from literate programming, it also draws ideas from code generation. Why should you use decumar instead of sweave?

  • you only need one file
  • it's always valid latex
  • caching is built in
  • you don't need to manually print ggplot2 and lattice plots
  • more types of output (figures, listing, ...)

Basic format

Decumar blocks look like this:

% BLOCKTYPE
%   OPTION1: value 1
%   OPTION2: value 2
%
% a <- 10
% a + b

latex

Decumar expects the following in your preamble:

\usepackage{alltt}
\usepackage{graphicx}
\DeclareGraphicsExtensions{.png,.pdf}
\graphicspath{{graphics-path/}}

blocks

Decumar currently supports the following block types:

  • DEFAULTS: set up default parameters

  • CODE: execute code, but don't display it

  • LISTING: display code, but don't execute it
  • CODELISTING: execute and display code
  • INTERWEAVE: interweave each line of code with its results

  • GRAPHIC: insert a bare graphic

  • FIGURE: insert multiple graphics in a floating figure
  • FIGLISTING: insert a figure and the display the code used to create it
