How to automatically load settings in R on OSX? How to find R_HOME, configure Rprofile.site, etc?

Question

I have a Macintosh and I am trying to automatically load packages, homemade functions, and use modified setting every time I start R. I believe this can be done with a file call

Answer 1

If you run getwd(), then you will see your R startup directory. On a mac it is typically /User/login_name That is where I leave my .RProfile where I load custom functions and also frequently used packages.
