Dear Eric
thank you for sending a reproducible example. I have run the same code
as you, and this produced a report without error messages and with all
elements that are supposed to be interactive (Figs. 3, 6, 12 and the
table) behaving as expected. The code and the report are here:
http://www-huber.embl.de/users/whuber/bioc-list/111008/
I have the following system parameters and session info as below, so my
recommendation is for you to update to more recent versions. More
comments see below.
$ pkg-config --version cairo
0.26

------------------------------------------------
The fact that for you Figs. 6 and 12 'work' -these are line plots- and
that Fig. 3 does not -this is a scatter plot- suggests that what you are
encountering is an aspect of the brittleness in the way that
arrayQualityMetrics (via SVGAnnotation) interacts with SVG files
produced by a third party (cairo). Essentially, that interaction is not
based on a defined protocol, but on unilateral reverse engineering.
SVGAnnotation is a fantastic piece of 'proof of concept' software, but
the situation is, of course, not satisfatory for applications that are
supposed to be used by many different people and on different platforms.
As soon as I can find the time, I will see how it can improved ( e.g.
gridSVG, where we have more control over the SVG ).
Best wishes
Wolfgang

> I have updated my packages, as per this list's posting guide, but to no avail. I have also searched the archives, and I discovered this thread where someone had a very similar problem (http://thread.gmane.org/gmane.science.biology.informatics.conductor/31622/focus=31666). I do not see there any solution. It's been about a year since that thread circulated, so I was wondering if anyone else has encountered this XML problem when running arrayQualityMetrics.

> It is not clear that my error is exactly the same as what James (from the above thread) encountered, but I'm thinking it's likely related. Maybe there is a parallel code block to the one throwing an error for James that wasn't fixed and is only now being observed. The differences from James's report follow:
>
> 1) I do get sections 4 and 5 in the index.html report file.
>
> 2) I have a notice beneath the caption for Figure 3 which reads: "Note: the figure is static - enhancement with interactive effects failed. This is either due to a version incompatibility of the 'SVGAnnotation' R package and your version of 'Cairo' or 'libcairo', or due to plot misformating. Please consult the Bioconductor mailing list, or contact the maintainer of 'arrayQualityMetrics' with a reproducible example in order to fix this problem."

I notice that some of my versions are slightly newer than those from the vignette.
