Build an error from an error type and data attributes

Usage

error(type, ...)

Arguments

type: character(1L) class type for error condition
...: Additional arguments passed to specific error function.

Value

A error condition of class type

Note

This function is only intended for use when parsing serialized output from text.

This function uses an error class to build an error object. It intentionally produces incomplete error objects, lacking the error backtrace call.

For signalling errors internal to the package, see err(). This function is used to provide a readable syntax to exported PACKAGES files, which are parsed using this function back into their respective error objects.

Examples

# given a DCF input such as

## Package: testpkg
## Version: 1.2.3
## Metric/word_count@R: error("missing_suggests", "wordcount")

# we want to parse (by evaluation) the output into our own error type
error("missing_suggests", "wordcount")
#> <error/val_meter_missing_suggests_error>
#> ! data derivation requires suggests: wordcount
