"Within R one can use source() to run a batch file of R commands, while R
and Rscript are run from the command line. Is this correct?"
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.
