loading GML files into R

Dear All, I am using sp and gstat to interpolate radiation data from the Dutch Radiation Monitoring Network. One of the goals of this project is to use inter operable data formats, in this case probably GML (Geography Markup Language). I have not found a package to parse GML files directly into R. Is anyone aware of a way to read GML files into R?
(Assuming GML vector data) Which platform are you on? If Linux/Unix/OSX, install GDAL with support in OGR for GML vector files, and use the rgdal package; this should work, but needs care in installing Xerces and other libraries. If Windows, use the binary rgdal package on CRAN to read a file converted from GML to one of the small range of drivers available - for example using the FWTools suite of Windows binaries - see ogrinfo and ogr2ogr in that suite.
