### This is the system Rprofile file. It is always run on startup.
### Additional commands can be placed in site or user Rprofile files
### (see ?Rprofile).

### Notice that it is a bad idea to use this file as a template for
### personal startup files, since things will be executed twice and in
### the wrong environment since user profiles are run in .GlobalEnv.
