Caveat: I work much more on Linux than Windows:
Rcmd.exeis a historical left-over as back in the day, you could not doR CMD somethingon Windows but needed the special executableRcmd.exe something. That is no longer the case, yet it is provided for backwards compatibility.Rterm.exeis also a holdover from the days whenRcmd.exewas used. Can be ignored these days.R CMD BATCHis a crutch that was needed in the days before littler andRscript.exe, and similarly lingering from old docs and habits..Rscript.exeis your friend for batch scripts; use it.- For everything else, there’s
R.exe.
Other than that, as Marek hinted, the reference manual is the wrong one among the six available manuals. Try the Introduction to R and the Installation and Admin manuals both of which have specific appendices for Windows.
