[Roxygen-devel] roxygen and subclassing? - Error in cdr(preorder.flatten.expression(expression))

[Mark Herzog]

Hello -

I am working with the devel source code (S4 support) and receiving the following error (includes roxygen call, in case that helps):

> roxygenize(package.dir=paste(work.dir,"/release/",sep=""),
+ roxygen.dir=paste(work.dir,"/release/pkg.roxygen",sep=""),
+ copy.package=FALSE,
+ unlink.target=FALSE,
+ use.Rd2=TRUE
+ )
Error in cdr(preorder.flatten.expression(expression)) :
  CDRing a null list

After doing some  investigation, I believe it is related to subclassing, (e.g. using 'contains' argument within a setClass statement).
Is this something that is not supported yet within roxygen, or am I doing something incorrectly? Is there a workaround?
I tried adding #' @nord to the line before the setClass statement, but that didn't seem to help.

> Sys.info()
                     sysname                      release
                   "Windows"                         "XP"
                     version
"build 2600, Service Pack 3"
                     machine
                       "x86"

Thanks for any insight,
Mark
