Thanks for this hint! (I did not have any 'results=xxx' before. Hence, it is 
clear why adding 'results = verbatim' had no effect.)

Yes, I have this command in the preamble of the Rnw file, but I get the 
waning message anyway :-(

I will uploaded the sampleSelection package (version 0.6-1) to 
If the CRAN servers run in the 'C' locale, all tests should pass without a 
warning and the updated package with the vignette will be available on CRAN 
soon. In this case, everybody can download the package and try to figure out 
the reason for the warning message. Any hints are welcome! 

BTW: It would be great if "R CMD check" could return a more informative 
warning message.
