[R] Error Using pm.getabst()

[larsenmtl@comcast.net]

R Users:

After installing Bioconductor, RSXML and all the relevant Win32 DLLs (libxml2, zlib, iconv), I receive the following error message when using pm.getabst()

Error in xmlRoot(absts) : no applicable method for "xmlRoot"

I receive this when using the example from help(pm.getabst).  

Downloading the target XML file, parsing it with xmlTreeParse and applying xmlRoot returns no error.

Your thoughts/suggestions are appreciated.
