git-svnimport: what to do after -i?

I am new to git. Last night I used "git svnimport -i" to import a svn project. It finished successfully. The only problem now is I can't seem to be able to checkout a working copy. In other words, I have a 'projectFoo' directory, with only .git in it, but not any actual working files. "git-branch" shows two branches, master and origin. "git-checkout master" returns successfully, but does nothing.

I guess that's because I used -i without fully understanding what it implies. Is there any way to checkout a working directory?

Thanks in advance for any ideas.
