safeExecute: Execute an expression with error handling

In nprcgenekeepr: Genetic Tools for Colony Management

Execute an expression with error handling

Description

Executes an expression with comprehensive error handling. On error, logs the error and returns a default value instead of stopping execution. This is particularly useful in Shiny reactive contexts where errors should be handled gracefully.

Usage

safeExecute(
  expr,
  module = "unknown",
  default = NULL,
  silent = FALSE,
  notify = FALSE
)

Arguments

expr	An expression to evaluate.
module	character. Name of the calling module for logging purposes.
default	The value to return if an error occurs. Defaults to NULL.
silent	logical. If TRUE, suppresses the error and warning logging. Defaults to FALSE.
notify	logical. If TRUE and in a Shiny context, shows a notification to the user. Defaults to FALSE.

Value

The result of evaluating expr, or default if an error occurs.

Examples

# Returns 4
safeExecute({ 2 + 2 }, module = "test")

# Returns NULL and logs error
safeExecute({ stop("Error!") }, module = "test")

# Returns custom default on error
safeExecute({ stop("Error!") }, module = "test", default = data.frame())
