Save command history from the menu (on macOS) or with command

Code $$\PageIndex{1}$$ (R):

savehistory("bugs.r")

(on Windows or Linux.)

Attention! Always save everything which you did in R!

Quit R typing

Code $$\PageIndex{2}$$ (R):

q("no")

Later, you can open the saved bugs.r in any text editor, change it, remove possible mistakes and redundancies, add more commands to it, copy fragments from it into the R window, and finally, run this file as R script, either from within R, with command source("bugs.r", echo=TRUE), or even without starting the interactive R session, typing in the console window something like Rscript bugs.r.
