and I did not have time then,
but last night.

I've commited a change to ESS' development version
which automatically starts R  if
- you are editing an S language buffer [ ess-language is "S" ]
  which should be the case for all R source files
- if your buffer has no associated ess process.

Consequently, this feature will be in ESS 5.3.8
