Within R one can use source() to run a batch file of R commands, while R CMD BATCH and Rscript are run from the command line. Is this correct?
Given these choices, when would I want to run a script within R using source(), and when would it be better for me to run it from the command line? Reading Appendix B.4 Scripting with R in R-info.pdf, ?Rscipt, and ?BATCH I get the impression that 'R CMD BATCH' reads from a named file and writes output to a named file and Rscript reads/writes to stdin/stdout using redirection. What are the pros and cons of each? When (or why) would I select one over the other?
