That is a bit vague. When discussing user interface behavior, it would  
make sense to be more explicit about keystrokes. It's not clear here  
that you aware that the Mac (which did start delivering this GUI  
pizzazz long before MS-Windows was even halfway stable) uses cmd-C and  
cmd-V as the to- and from-clipboard key operations, rather than crtl-C  
and ctrl-V?

??"clipboard"

Brings up two hits on my machine one for connections and one for  
TkCommands. The first has a section on functions to access the  
Clipboard from R.  The second help page should appear if you have  
tcltk loaded, although I don't at the moment so I cannot test that.

?connections
?TkCommands  # probably

There is a specific help list for Mac questions and a lot of the  
really knowledgeable people read it more regularly than r-help.
