[R] Creating .Rout.save files for package subdirectory "tests"

[Arne Henningsen]

Hi,

I added the "tests" subdirectory and a test file (say "myTest.R") to our 
"systemfit" package. Up to now I create the "myTest.Rout.save" file with 
> R CMD BATCH --vanilla myTest.R myTest.Rout.save

However, "R CMD check" reports two differences between myTest.Rout.save and 
the output of myTest.R:
a) myTest.Rout.save contains following extra line at the beginning of the 
file:
> invisible(options(echo = TRUE))
b) myTest.Rout.save contains the following 2 extra lines at the very end of 
the file:
> proc.time()
[1] 1.80 0.07 2.00 0.01 0.00

Everytime I change myTest.R and create a new myTest.R.save file I have to 
delete these 3 lines by hand. I could do this e.g. by a script using "sed", 
but I wonder if I can start "R CMD BATCH" with an option that suppresses any 
commands that are not in the input file, i.e. "invisible(options(echo = 
TRUE))" and "proc.time()".
Or what is the easiest way to create .Rout.save files?
(I am using R 2.0.0 on a i686 PC with SuSE Linux 9.0)

Thanks,
Arne
