Evaluate code with unified error handling (and consistent warning reporting).
On error, prints a CLI message (unless quiet = TRUE) and returns NULL.
Usage
safe_execute(expr, fail_message = "An error occurred", quiet = FALSE)
Arguments
- expr
Code to evaluate.
- fail_message
Message to display if an error occurs. Default: "An error occurred".
- quiet
Logical. If TRUE, suppress messages. Default: FALSE.
Value
The result of the expression if successful; otherwise NULL.
Examples
safe_execute(log(1))
#> [1] 0
safe_execute(log("a"), fail_message = "Failed to compute log")
#> ✖ Failed to compute log: non-numeric argument to mathematical function
#> NULL
