[Bioc-devel] import except on Window Machine

Michael,

For some reason,  adding except clause in import in the NAMESPACE file gives error on window server, although it runs fine on Linux and Mac OS X.

Here is the line that gives error.
import(S4Vectors, except=c(fold, values))

Did I miss something? Thank!

Best regards,

Julie
