I'm quite sure the 'destfile' argument of download.file() is a file not a directory. Example:

> download.file("http://www.r-project.org/index.html", destfile="foo.html")
> file.info("foo.html")

         size isdir mode mtime ctime foo.html 785 FALSE 666 2008-03-18 08:54:19 2008-03-18 08:54:11

                       atime exe

foo.html 2008-03-18 08:54:19 no

So you probably saved the downloaded file as 'geoDat' in the root directory '/'.
