Undo button/ ctrl functions not working

[11christine11]

Hi guys,

I’ve just installed Rstudio for windows and i’m unable to undo a line of code in the console area using the edit buttons at the top or using ctrl z /ctrl x.

I’m a complete beginner with this and any help would be appreciated.

Thanks

What was the line of code?

If you're editing a text file, like an .Rmd or .R script, undoing typing is the same as with any text editor, just ctrl+z.

The R console works a bit differently. The console is the place where R is waiting for you to tell it what to do, and where it will show the results of a command. So to undo a command giving to the console you have to provide a command that undoes it. For example, below I assign 1 to a, and then undo that.

a <- 1
a
#> [1] 1
rm(a)
a
#> Error in eval(expr, envir, enclos): object 'a' not found
