How to change the default text editor in R when on Linux?

Question

I program using R on Linux, and every time I want to edit a function by typing

fix(FunctioName) 

The VI editor is used, and for me it is not so convenient, I want to change it and make it different, for example, nano. I connect to our school server, so I only have a shell, no graphical interface.

Thanks in advance.

Answer 1

As always, export your desired editor to $EDITOR or $VISUAL before starting.

Answer 2

Or in R, to override the environment variable:

 options(editor = "nano")
