factory: Catch errors and warnings and store them for subsequent...

In russmisc: A repository for a variety of useful functions.

Description

Factory is not my code. Factory generates a function which is appropriately wrapped by error handlers. The result produced is a list. This is a nice way to recover from a loop problems that may have occured during loop evaluation. Check the references for additional related functions. I have not included the other factory functions because they did not play well with the return item as an S4 object.

Usage

  factory(fun)

Arguments

fun	The function to be turned into a factory

Value

list[3]: item 1 is the result from the function and $warn and $err contain warning and error messages respectively.
