OK - this was your test that the file existed. read.dbf(cities.dbf) might have been more helpful. To check that there is no spaces in path names problem here, I tried: library(maptools) getwd() [1] /home/rsb/tmp/bigshape/R scripts list.files(pattern=shp$) [1] co37_d90.shp getinfo.shape(co37_d90.shp) Shapefile type: Polygon, (5), # of Shapes: 104 shp - read.shape(co37_d90.shp) Shapefile type: Polygon, (5), # of Shapes: 104 admittedly on Linux and with an up-to-date package. I have also checked on Windows XP, also with current maptools and R 2.6.1, with the same result. Seeing your sessionInfo() would show both your platform and package version.
