[R-SIG-Mac] How to find the path for a file to be read with read.table() in a Mac

[Parkhurst, David F.]

I’ve several times to figure this out with no luck.  I’ve moved a tab delimited text file (created from excel) to the desktop to simplify the path.  If I click on the file and ask Get Info, it lists “Where” as  iCloud Drive > Desktop.  If I copy that to the clipboard and paste that into a read.table command in the R console, it comes up as /Users/DFP/Desktop.  But if I try read.table("\\Users\\DFP\\Desktop\\moabsitechem"), I get No such file or directory.  How can I get that file into a data frame?

Is there some place in my Mac that I can put the file so I could enter just the file name, and not the whole path?
