It means the operation failed.  Suppressing the output is easy, but it 
probably makes more sense to try to figure out why R thinks it failed 
and you think it didn't.  R will report that if it can't open the source 
or destination file, or if the file size of the destination file after 
copying is different than the size of the source file.
