get_result

Read the result object from the output file, or the error

Description

Even if an error happens, the output file might still exist, because saveRDS() creates the file before evaluating its object argument. So we need to check for the error file to decide if an error happened.

Usage

get_result(output, options)

Arguments

`options`	The context, including all parameters.
`out`	List of the output object from `run()` and the name of the result file to read. For the error file, `.error` is appended to this.

Value

If no error happened, the result is returned. Otherwise we handle the error.
