"Within R one can use source() to run a batch file of R commands, while R

Yes.
Bert,
Thanks for confirming.
I think your query answers your query: You use Rscript when you want to use
R in the command environment, perhaps as part of an analytical pipeline;
and you source an R file when you want to work within R.
That's a given. Why would I prefer Rscript over R CMD BATCH, or
vice-versa? I did not see much difference between the two in their help
files.

Rich
