active pdf/annotated visualization RFC
Hi In terms of related plans: over the (southern) summer I plan to have a student take a look at producing SVG output from R. There are many possibilities for embedding metadata within such output. You may want to talk to Naras (Balasubramanian Narasimhan naras@stat.stanford.edu) who has worked on the SVG stuff a bit already and has thought a bit about how to include the metadata. Paul

How can R users take advantage of the "active PDF" paradigm for annotation of statistical graphics? The basic objective is to take a small number of locations on a graph and hyperlink them -- add persistent information to the pdf rendering of the graph so that when the user clicks on the location, a browser is (started if necessary and) pointed to a URL specified by the persistent information. One possibility is to generate pdf graphical documents with the existing PDF driver in R and use external software to introduce active links. We don't know at present what external software would be useful for this. Another possibility is to establish a "text" like function for use with the pdf driver that allows the user to give vectors of x and y coordinates and a vector of metadata to be bound to the coordinates as active link targets. -- This is a request for advice/comments/plans related to annotated visualizations created with R but exportable to non-R users. Other graphical formats and languages not mentioned here may be relevant and comments to this effect are welcome. -- --- Vince Carey, PhD Ass't Prof Med (Biostatistics) Harvard Medical School Channing Laboratory - ph 6175252265 fa 6177311541 cell 8572126768 181 Longwood Ave Boston MA 02115 USA stvjc@channing.harvard.edu -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
