How to prevent execution of further code steps after error?

Question

How can I make sure that after I \"catch\" an error and log it no further code steps are executed (I do not want to use q())?

My usage scenario is like this: - do so

Answer 1

Just wrap curly braces around it

>     {
+       handleMySimpleError<-function(e, text) {
+           # Let's log the error
+           print(paste0(text, ": ", e))
+           # This should stop execution of any further steps but it doesn't
+           stop("Now, stop. For real.")
+       }
+       print("Starting execution...")
+       tryCatch(
+           stop("My simple error."),
+           error=function(e) {handleMySimpleError(e, "could not finish due to")}, finally=NULL
+       )
+       print("Successfully ended execution...") 
+     }
[1] "Starting execution..."
[1] "could not finish due to: Error in doTryCatch(return(expr), name, parentenv, handler): My simple error.\n"
Error in handleMySimpleError(e, "could not finish due to") : 
  Now, stop. For real.
