Hi,

I'm having trouble using the SVGAnnotation package with R 3.0.0. In
particular, I'm unable to run any of the examples available at
http://www.omegahat.org/SVGAnnotation/tests/examples.html ; these all
worked AFAIK with R prior to 3.0.0. Here's some example output from trying
to run the first example on the page:

> ?SVGAnnotation
> svg("pairs_link.svg", 14, 10)
> pairs(mtcars[,1:3], cex = 2)
> dev.off()
RStudioGD
        2
>
> doc = xmlParse("pairs_link.svg")
> linkPlots(doc)
Error in tmp[i] : invalid subscript type 'list'
> saveXML(doc, "pairs_link.svg")
[1] "pairs_link.svg"

Note the error occuring with 'linkPlots(doc)'. Tracebacks suggest the error
occurs in 'getPlotRegionNodes'; however, I am not familiar enough with the
package to debug further.

> sessionInfo()
R version 3.0.0 (2013-04-03)
Platform: x86_64-apple-darwin10.8.0 (64-bit)

locale:
[1] en_CA.UTF-8/en_CA.UTF-8/en_CA.UTF-8/C/en_CA.UTF-8/en_CA.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

other attached packages:
[1] SVGAnnotation_0.93-1 XML_3.95-0.2

loaded via a namespace (and not attached):
[1] tools_3.0.0

Any insight would be helpful.

Thanks,
-Kevin
