Hi, is there a capability in R/bioconductor for specifying hyperlinks from a , say, postscript or pdf plot. For instance, when I produce n by p image matrix with log2ratios and with all the clone names for the columns listed, is there a way to create a mark-up so that by clicking on a clone name to be taken to golden path (UCSC) info on the clone? If that is not possible, what would be the closest thing which is implemented? Thank you Jane ********************************************************************** **************** Jane Fridlyand, Postdoctoral Scientist UCSF Cancer Center, Box 0128 San Francisco, CA 94143-0128 Office: Room N412 Tel: (415)514-3302 Fax: (415)502-3179 ********************************************************************** ****************

Restriction may be the wrong word, but the general idea is solid, I think (i.e. mailing a hyperlinked PDF file to collaborators, for example).

Being able to generate active PDFs is definitely desirable (for posting or mailing to people who neither know nor care about R :-)). I don't see the current device driver model handling this very well. > I think the general annotation problem (thinking along the lines of > Vince) would be worth looking at. > > best, > -tony > > -- > A.J.

I don't see > the current device driver model handling this very well. ok, i am warming up to this idea, but i suspect that the density of hyperlinks to be handled by existing designs would be pretty light (at most a few links per line of narrative text or per embedded image). what jane is describing sounds very dense, and the quantity of metadata in a chip image could be substantial even if only one sort of link resolution were required ([x,y] to locuslink, e.g.). one would want to do the mapping from the geometry of the document (image) to the genomic annotation outside the document -- so i would assume that the document and a database would be involved at a minimum. i made a cursory search on active pdf and a check of the adobe site. i don't see anything immediately available for prototyping. one approach is to generate the pdf image in R and then apply some adobe tool to introduce a hyperlink. i would assume distiller could do this but i do not have access. if this worked we would then consider how best links could be introduced en masse.

currently i am specifying clone names with a very small cex size and passing images on the biologists in the pdf format who then open it up in the Photoshop which i guess has a very good ability to zoom in (maybe adobe acrobat does too: i just don't have the full version). In any case focusing the mouse on the right clone names is not a problem for them. But i guess Vincent's concern is the file size with hyperlinks encoded for each clone name, is it right? Sparcing links across the genome would also be an option of course. What would be a reasonable number of hyperlinks per image?

I'm a bit confused (maybe others are, as well) if you mean "picture of a chip", or just "stuff in a PDF file"? If you are planning on clicking on a "spot", yikes, but just annotating text via hyperlinks, as long as its readable, should be fine... (well, readable and "mouse-able"). best, -tony -- A.J.

BTW it would probably be sensible to cast this problem for r-devel, as it is a good problem of general annotation of statistical visualizations.
