Adding a table of contents to PDF with R plots

Question

I\'m creating a larger number of plots in R and save them as PDF (using grDevices / pdf). Is there an easy way to add a (meta-data) table of contents to the PDF as it is created

Answer 1

The only way I know is with LaTeX, but you don't necessarily need Sweave; perhaps you could just generate the LaTeX file directly with your RPython code. If you've got two pictures which are 6x6 (the default size) named tmp-001.pdf and tmp-002.pdf, this is how you'd make a section called Section A with two subsections for the two pictures.

\documentclass{article}
\usepackage[paperwidth=6in, paperheight=6in, margin=0in]{geometry}
\usepackage{hyperref}
\usepackage{graphicx}
\parindent 0pt
\begin{document}
\pdfbookmark[1]{Section A}{anchorname_aa}

\pdfbookmark[2]{plot aa}{anchorname_aa}
\includegraphics{tmp-001.pdf}

\newpage
\pdfbookmark[2]{plot bb}{anchorname_bb}
\includegraphics{tmp-002.pdf}

\end{document}
