dear Ivan,
Thanks for the reply. One last question:
1. How do you debug if there is an error, particularly if I run the script
from the BASH prompt? The closest I have come to debugging a script is when I
source the script in Rstudio. There everything is intiutive...but from the
Linux prompt?
Thanking you,
Yours sincerely,
AKSHAY M KULKARNI

When using Rscript: to stderr, to be precise.
When using R CMD BATCH: to the Rout file.

May I shamelessly plug my own package, depcache? Using its cache()
function, you can save intermediate objects into *.rds files in a
relatively transparent manner. By default, they are stored in a
subdirectory of the working directory. A downside is that I haven't
come up with a useful cache expiration strategy yet.
A more involved approach that will also let you access your
intermediates is provided by the "targets" package, not only on CRAN
but also peer-reviewed by rOpenSci.
