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.
