Hi Bernhard,

Thanks for the note.

| a couple of weeks ago BDR reminded package maintainers of a change with respect to BIC. He suggested for 'urca' the NAMESPEACE insertion you provided below. The latest CRAN Package Check does not indicate an error for 'urca'. If I recall correctly, the package fUnitRoots was mentioned in that email of BDR, too. Maybe the required changes have not implemented in there?

Seems like it, and the R-Metrics team appears to be too busy before the
upcoming retreat.

Would you have a suggestion as to how to fix this on the side of fUnitRoots
so that it builds again?  Else I may have to withdraw the package.

Thanks, Dirk
