[R] passing command line arguments to 'R CMD BATCH myScript.R'

[Brahm, David]

I have never understood the difference between 
> R CMD BATCH --vanilla --slave myScript.R outFile.txt
and
> R --vanilla --slave < myScript.R > outFile.txt

I use the latter method, and then the --args construction works great:
> R --vanilla --slave --args myArg1 myArg2 < myScript.R > outFile.txt

In fact, I define "R --vanilla --slave --args" to be an environment
variable $R, and then it's just
> $R myArg1 myArg2 < myScript.R > outFile.txt
