Interrupting R Script?-CodePudding

I've seen this question which answers how to exit a function when needed. But I'm working with a complex R script which I'm debugging. I run it in VScode, and would be nice if there was a command to simply stop running the script altogether, as using exit(1) in python. See the code below for example.

rm(list=ls()) # Ensuring workspace starts off clean

a <- 1 # Do stuff I'm confident about
b <- 2 # Stuff I need to check if worked

cat(b)

Function_to_Stop_Execution_Here() # What can I for about this?

Stuff_I_dont_want_to_run()

CodePudding user response：

Try using quit or q. ]

However, quit will also completely quit R. If you want to return to the R console after your function to stop execution, you can use stopifnot to purposefully throw an error.

CodePudding user response：

If you want to stop a script, use stop (which raises an error).

If you possibly want to restart, but need to examine the working state, consider browser

a <- 1 # Do stuff I'm confident about
b <- 2 # Stuff I need to check if worked

cat(b)
browser() # or stop("Some error message")

But if there is stuff you don't want to run below this, it's probably best to delete it.

CodePudding user response：

You might use quit() with argument save='ask' and type 'c' in console then.

a <- 1 # Do stuff I'm confident about
b <- 2 # Stuff I need to check if worked

cat(b)

quit(save='ask')
