Error Handling

R provides a few tools for handling errors. The function try() can be used to catch errors and continue the execution of your code. Here’s how it works:

x <- try(log("a"), silent = TRUE)
if(inherits(x, "try-error")) {
  print("An error occurred.")
} else {
  print(x)
}
## [1] "An error occurred."

In this example, if an error occurs in the log("a") expression, try() catches it, assigns the result to x, and the code continues to execute. The inherits(x, "try-error") check can then be used to see if an error occurred. ```
