Both "show.output.on.console" and "invisible" are Windows only arguments 
of system(). This is a bug in the package that needs to be reported to 
the package maintainer, Diethelm Wuertz (CCing).

It means that the package meintainer decided not to run this part of the 
examples by R CMD check, hence it is unchecked (and nobody traced the 
bug before).
