You want to have a look at the R Spatial Task View for starters... GML files can be read by the rgdal package's readOGR function. But be warned.... GML is a complex beast.
For example, I downloaded canvec_gml_AB_EN.zip from that site, it unzips to a GML (and an xsd) with a lot of layers, some of which aren't spatial. Using the ogrinfo command line tool from the gdal library I can see the layers: $ ogrinfo -so AB_EN.gml Had to open data source read-only. INFO: Open of `AB_EN.gml' using driver `GML' successful. 1: d_y_n (None) 2: d_y_n00 (None) 3: d_y_n01 (None) 4: d_y_n02 (None) 5: d_y_n03 (None) 6: d_y_n04 (None) 7: d_y_n05 (None) 8: d_y_n06 (None) [etc etc] 191: d_y166 (None) 192: d_y167 (None) 193: EN_1360049_0 (Multi Point) 194: EN_1360059_2 (Multi Polygon) 195: EN_1360049_2 (Multi Polygon) 196: EN_1340009_0 (Multi Point) 197: EN_1360059_0 (Multi Point) 198: EN_2170009_0 (Multi Point) 199: EN_1120009_1 (Multi Line String) 200: EN_1180009_1 (Multi Line String) So thats 192 non-spatial layers and a bunch of points n lines n polygons layers. Let's read one: m = readOGR("./AB_EN.gml","EN_1360059_2") plot(m) makes a map. Its a bunch of very small polygons, hard to see really! Further questions will be welcome at the R-sig-geo mailing list, where we whine about file formats on a daily basis.
