Subversion repository layout

I need a little advice on setting up my Subversion repository. The terminology and options in control panel confuse me. Basically, I think I just want a regular setup with one repository containing several projects. I would like one path to contain private projects and one path to contain public (read-only) projects. My initial attempt was to use control panel to make two projects:, when control panel talks about creating “projects”, it seems to me that they really mean “repositories”. At least that’s what it ended up being; two separate repositories named private and public. That’s not what I wanted - or I don’t think it is.

So could anybody advise me on how to setup one repository with the requirements that one path be public and another private?
