R won’t complain if the class of your condition doesn’t match the function, but in real code you should pass a condition that inherits from the appropriate class: "error" for stop(), "warning" for warning(), and "message" for message(). Même si une instruction ou une expression est syntaxiquement correcte, elle peut générer une erreur lors de son exécution. If running R v1.7.1 or before … in finally or ANY, such exceptions should extend (inherit from) the class try-error, which is for instance the case with all stop() and throw() generated exceptions. In R Programming, there are basically two ways in which we can implement an error handling mechanism. Becker, R. A., Chambers, J. M. and Wilks, A. R. (1988) The New S Language. Robust in the sense that we want it to handle situations where something either goes wrong (error) or not quite the way we planned it to (warning). One rule in online web development is to never trust user input (the usual quote is all user input is evil).While there aren’t security issues in R that warrant as strong of a concern, it is still important that user input is checked if for no other reason than to provide thoughtful feedback when something is wrong. Problèmes avec les parcelles en boucle; mais je ne comprends toujours pas. The warning message as character string, invisibly.
