How to eliminate Roxygen warning about "No name found..."?

I'm calling roxygenize() with parameter use.Rd2 = TRUE. I have a file testcase.R where I create a simple S3 object using R.oo. Here's the contents of the file. There's nothing for roxygen to do here, and it should ignore th开发者_如何学Ce contents:

library( R.oo )

setConstructorS3( "TestCase" , 
function() 
{  
    extend( Object() , "TestCase", 
            .parameters = list() ,
            .validationData = list()
          )
} )

And here's the error:

Error in parse.name(partitum) :
  (converted from warning) No name found for the following expression in E:/mypackage/R/te
stcase.R line 1:
  `library( R.oo ) . . .'
Calls: roxygenize ... <Anonymous> -> maybe.call -> do.call -> <Anonymous> -> par
se.name

How can I eliminate the warning? Per suggestions in other posts, I added the following as the first line, but it didn't work:

Upgrading to Roxygen2 eliminated the error.
