Hey All,
I'm a new user here and just getting into R. Now I have the issue that I cannot click on lines I already ran in the console. Meaning I cannot eddit lines Previously run. That is an issue as it makes following my class really difficult as I constantly need to rewrite whole lines in very short amounts of time.
If I understand you correctly, what you are seeing is normal. You can move through the console history with the up and down arrow keys, and you can highlight previous commands and copy/paste them, but you can't click on a previous command and edit it in place.
You can edit previous commands that you type in the Code pane, which is typically at the top left of the RStudio screen after you select the menu File -> New -> R Script.
