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:

Hi everyone,

I'm trying to diagnose a problem in my R package, but it is a little tricky since it seems to occur only with the Mac OSX CRAN binary build.

My package starts a Rook server and opens a browser. On my own system (details below), when I build the package, I have no trouble. The Rook server starts and the page loads in the browser. 

However, if I've installed it from CRAN, I get the following error when trying to open my Rook interface:

######
Warning message:
In normalizePath(file.path(root, path_info)) :

path[1]="/Volumes/XT3/Rdev-web/QA/Simon/packages/leopard-universal/Rlib/2.15/BayesFactor/.//www/warning.html":
No such file or directory
######

I assume "Simon" refers to Simon Urbanek.
 
www/warning.html is the file Rook is attempting to open. This looks like a path from the CRAN build machine. How did this make it into my package? I'm sort of baffled, and I don't know how to diagnose it. 

To replicate:
#########
install.packages('BayesFactor')
library(BayesFactor)
data(puzzles)
aovGUI(y = puzzles$RT, dataFixed = puzzles[,3:4], dataRandom = puzzles$ID)
#########

When I set 
options(warning.expression = quote(recover()))

I see where the problem lies. In the frame "15: file_server$call(env)", the variable "root" is defined as:

Browse[1]> root
[1] "/Volumes/XT3/Rdev-web/QA/Simon/packages/leopard-universal/Rlib/2.15/BayesFactor/."

But "find" returns nothing for "root":
Browse[1]> find("root")
character(0)

In the Rook source here (https://github.com/jeffreyhorner/Rook/blob/master/Rook/R/File.R) is the reference to "root", but I'm not sure where the specific path value comes from.

Further information:

sessionInfo()

My Rook version is 1.0-8 and I'm running Mountain Lion (10.8.2). Any hints would be appreciated.

Best,
Richard
