Wow, that is embarrassing. For the record, I read the fine manual
section on 'ESS for the S family', and tried M-x ess-<tab> to generate a
list of all ESS functions that I could scan for clues. Now that I know
the answer, I searched for the phrase r-mode in the entire text of the
ess manual, and it doesn't appear (excepting as part of the command
ess-R-mode-font-lock-keywords). 

Could I humbly request that some reference to R-mode be added to the
info file? (info "(ess)ESS(S)--Editing files") seems like the best place:

   ESS[S] mode should be automatically turned on when loading a file
with the suffices found in ess-site (*.R, *.S, *.s, etc). **For files
with non-standard suffices, the mode may be explicitly started with the
command M-x R-mode.** However, one will have to start up an inferior
process to take advantage of the interactive features.

Or is there some other way to discover this function that I
overlooked?

Thanks!
