Re: [Rd] paths and Rook problems only in OSX CRAN binary package?

Richard,

I was away hence a late response.

The problem is that you are creating aovApp directly at compile time, so it will hard-code the root path as the initialized object is lazy-loaded. This means that the package will only work in the library that it was complied into, it won't work anywhere else and thus it cannot be distributed as a binary package.

There are many possible fixes, probably the easiest is to simply make aovApp a function so the actual objects won't be lazy-loaded:
