Hi R'ers:
I would like to setting up a .Rprofile file with
setwd("C:/R_WorkDir")
set.seed(12345)
options (prompt "> R ")

Can you help providing the code or instructive link,
I've find many links, but I can't figure it out?

Thanks.

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.
