Yup. The FAQ is imprecise there. The exact logic is
R_LoadProfile(R_OpenSiteFile()); /*if existing*/
R_LoadProfile(R_OpenInitFile()); /*if existing*/
Note that if all three are executed if they exist. However, at least
the system init file doesn't do anything that can't be undone later
The first reads $RHOME/library/base/R/Rprofile which you are not
supposed to tamper with (or else *we* wouldn't be able to tamper with
Thes second looks in $RPROFILE, and if it isn't there, in
The third looks in ./.Rprofile and $HOME/.Rprofile in that order.
