Utility function to output an error — wrap

This function is used to capture errors, typically inside a tryCatch() statement and output them in a clean and readable way. The function provides line-wrapping, with a configurable width. When printing the error message, it prefixes the text with "#E> " to make it easier to look for the error.

Usage

wrap_error(e, wrap = 50)

Arguments

e: The error to wrap.
wrap: How many characters per line before wrapping.

Value

The original error is returned invisibly.

Examples

tryCatch(stop("This is an error"), error=wrap_error)
#> #E> This is an error
