(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.
