From my perspective, which is a unix-alike perspective, Rscript makes R useable in exactly the same way as other unix style scripting languages such as perl, tcsh, bash, etc. This is useful, and a good thing. If I remember (and understood) correctly, it is why Rscript was introduced, later in R's history than BATCH.
Don, As a linux-only user for more than two decades I really appreciate the value of running scripts from the command line. For a current project, after extracting 29 years of data from PDF forms I ran them through a bash shell script (passing the name of the source file as $1) that calls two sed and six awk scripts. The output is ready to be read into R.
If I want to pass custom parameters to the script (script-specific parameters of my own that I put on the command line), the syntax for either supplying them or parsing them might be different. I'm not sure, since I don't do this very often, and never use CMD BATCH. But it would be worth checking.
This is what I need to work out now for Rscript: how to set positional or named parameters on the command line with the source file name and the R data.frame name. Thanks for your comments.
