在Mac上为R函数创建键盘快捷键？

Question

I would like to create a keyboard shortcut to run an R function in an existing R session. How can I do this on a Mac?

My first idea was to use

% R --slave < foo.R

and create a keyboard-shortcut to a shell script with this command.

But this starts a new R session. Is there a way to send a command to an existing session from shell?

Answer 1

I can think of two similar ways to do this; neither is necessarily elegant, but both get the job done.

• Run a tmux session which consists solely of an R session, and write a script that uses tmux send-keys to send your command.

• Similarly, you could set up a dedicated iTerm2 session to receive the keys. If you were in iTerm2 already, you could set up a keyboard shortcut to send your command. Outside iTerm2, I think you're looking at some applescript.
