More serious departures from social norms carry labels such as misbehavior and labels from the legal system, such as misdemeanor and crime. (See deviance.) Gaffes and faux pas can be labels for certain instances of this kind of error. In human behavior the norms or expectations for behavior or its consequences can be derived from the intention of the actor or from the expectations of other individuals or from a social grouping or from social norms. The second time it would be a mistake since I should have known better. If, however, I try to park in an area with conflicting signs, and I get a ticket because I was incorrect on my interpretation of what the signs meant, that would be an error. Now, say that I run a stop sign because I was in a hurry, and wasn't concentrating, and the police stop me, that is a mistake. A 'mistake' is an error caused by a fault: the fault being misjudgment, carelessness, or forgetfulness. One reference differentiates between "error" and "mistake" as follows:Īn 'error' is a deviation from accuracy or correctness. An error could result in failure or in a deviation from the intended performance or behavior. In statistics, "error" refers to the difference between the value which has been computed and the correct value. The etymology derives from the Latin term 'errare', meaning 'to stray'. In some usages, an error is synonymous with a mistake.

You could then press Esc or the Stop-Button in RStudio to interrupt the program.This article needs additional citations for verification. If your goal is simply to be informed when something goes wrong, before a lot of code is run in vain, maybe you could define a function similar to stopifnot() that will just go into an endless loop, if there is an error. Even if stopifnot() is called inside of a function, all the lines after that function call will still be evaluated. Rstudio is just running one line after the other. I don't think that there is a way to prevent RStudio from running all the lines, when you select a section and press Ctrl+Enter. To switch-off this behaviour, just re-set the error option to NULL: options(error=NULL) # some more input: we don't want this to be run or to appear in the console # Set the 'error' option to execute our pause function: # Define our 'eat_input' function to prevent output of subsequent, not-run input: To make this slicker-still, we can output a 'cursor up' character sequence after each 'eaten' line, which erases each of them as the next one is output, so that the not-run lines don't clutter up the terminal/console.Įxample code: # Define our error-handling pause function:Ĭat("Paused: press ctrl-C (or Escape key in Rstudio) to continue\n")Ĭat("(any subsequent code will be ignored)\n") However, we can prevent this by defining a function that will 'eat' all of these so that they don't get run. Normally, R will then move-on and execute any subsequent commands. One way to solve this is to configure the R 'error' option to run a custom function when an error is encountered.Īn example error-handling function can pause execution of R using Sys.sleep and await user input (for instance, breaking-out of the running function by pressing ctrl-C, or Escape in R-Studio on my Mac).
