Quoting from ?Startup:

,----
| [...] unless ‘--no-init-file’ was given, R searches
| for a user profile, a file of R code.  The path of
| this file can be specified by the ‘R_PROFILE_USER’
| environment variable (and tilde expansion will be
| performed).  If this is unset, a file called
| ‘.Rprofile’ is searched for in the current directory
| or in the user's home directory (in that order).  The
| user profile file is sourced into the workspace.
