Since you are on Windows, please read:
file.show(system.file("README.windows", package="rgdal"))
One suggestion is to use ogr2ogr in the latest Windows binary FWTools
collection for example through system() for doing this within R - see the
GDAL site for links. Building the package yourself using FWTools may be
useful if you need to know, if you don't, use an alternative. On
Unix/Linux/OSX with the underlying libraries present, this would have
worked (with the curiosity that only the KML driver is default write only,
but returns the read/write capability even if it cannot read - the choices
it gets are read or read/write, but no write-only.

Hi,
I've been trying to convert a vector kml-file to an ESRI shape with readOGR(),
but I don't manage to read the kml-file. Can anyone help me with this?
http://www.gdal.org/ogr/ogr_formats.html mentions at KML that "read
support needs libexpat". Further it says "KML reading is only available
if GDAL/OGR is built with the Expat XML Parser, otherwise only KML
writing will be supported."
Maybe this was missing while your gdal/rgdal was built?
