[R] File names for mac newby

[R. Mark Sharp]

Open the terminal application in the Utilities folder. Select the file you want to use in R in a Finder window and drag it to the terminal applications command line prompt and then release the file. The absolute path of the file will be entered in the command line of the terminal’s window. Though this absolute path will work, relative paths are often preferred.

That's a file within one called house which is within one called ah.  That may further be in one called  Documents.  I tried various lines like:
