Look at help(Startup) which has an example at the end:

 ## Example ~/.Renviron on Unix
 R_LIBS=~/R/library
 PAGER=/usr/local/bin/less

 ## Example .Renviron on Windows
 R_LIBS=C:/R/library
 MY_TCLTK="c:/Program Files/Tcl/bin"

 ## Example of setting R_DEFAULT_PACKAGES (from R CMD check)
 R_DEFAULT_PACKAGES='utils,grDevices,graphics,stats'
 # this loads the packages in the order given, so they appear on
 # the search path in reverse order.

But note the spelling: Renviron with lower case e. Just use a text editor and edit the file. Also note that R has a variant in one of its system folder etc/ below its RHOME:

edd@bud:~$ R RHOME
/usr/lib/R
edd@bud:~$ cat $(R RHOME)/etc/Renviron.site
##                                              Emacs please make this -*- R -*-
## empty Renviron.site for R on Debian

Hm. Looks like I wrote that for the Debian package and it does always exist. You can still copy it.
