You can use a tryCatch () function in R to return the value of some expression or produce a custom message if a warning or error is encountered. This function uses the following basic syntax: my_function <- function(x, y){ tryCatch( #try to do this . { #some expression. }, #if an error occurs, tell me the error . error=function(e) {

R uses functions for implementing try-catch block: The syntax somewhat looks like this: result = tryCatch({ expr }, warning = function(warning_condition) { warning-handler-code }, error = function(error_condition) { error-handler-code }, finally={ cleanup-code })

In tryCatch () there are two ‘conditions’ that can be handled: ‘warnings’ and ‘errors’. The important thing to understand when writing each block of code is the state of execution and the scope. Excerpting relevant text from the ?tryCatch documentation:

Utilisez tryCatch pour gérer les conditions d’erreur dans R. Trois types de conditions intégrées sont fournies dans le langage R, qui peuvent être levées en tant qu’exceptions du code. Classiquement, les plus graves sont appelées erreurs, ce qui met généralement fin à la fonction ou à l’arrêt de l’exécution.

In a previous post, we looked at error handling in R with the tryCatch() function and how this could be used to write Java style try-catch-finally blocks. This time we’ll look at what can be done with the try() function and how we can easily process warning and error messages to take appropriate action when something goes wrong.

The tryCatchLog package provides an advanced tryCatch function for the programming language R. The main advantages of the tryCatchLog function over tryCatch are: Easy logging of errors, warnings and messages into a file or console.

In this article, I have explained the tryCatch() function, its syntax, parameters, and how to use it to catch and handle errors, warnings, and messages without interrupting an R script. I also covered the implementation of nested tryCatch() and using tryCatch() within loops.
