[R-sig-Debian] pkg/tests: how to run them with --vanilla

[mat]

Hello

I recently submitted an update of a package, and received error reports 
from CRAN maintainers concerning the pkg/tests section:

  I always used to run the .Rout.save files with R CMD BATCH xxx.R So it 
seems I should rather do it with R --vanilla... I tried:
cat xxx.R| R --vanilla --slave > xxx.Rout.save

But this gives files without the ">", and then it gets reported in the R 
CMD check... What would be the good way to do?

Secondly, I always got this error that the R CMD BATCH run in french, 
but the R CMD check in english. I have been told I should change to 
language=EN. But how do I do this in Linux? I just added:
Sys.setlocale("LC_ALL","en_US.UTF8")
Sys.setlocale("LC_CTYPE","en_US.UTF8")
Sys.setlocale("LC_MESSAGES","en_US.UTF8")

in the .Rprofile... it this right?

Thanks!!
