icd9InvalidActions

Some functions accept <code>invalidAction</code> argument, but require non-default validation, but the vast majority will honor the default of 'ignore.' Ignore may lead to downstream errors, since bad data may arrive in internal functions, however, this is the fastest option. A typical use-case of this package would involve validation and cleaning steps (with validation), followed by repeated analysis (as fast as possible, with minimal validation).

This package allows accurate manipulation, validation and
    comparison of ICD-9-CM (clinical modification) codes. Although ICD-9 codes
    appear numeric, this is not the case, since trailing zeroes, and a mixture
    of decimal and non-decimal "short" format codes exist. Tools to map ICD-9
    codes to co-morbidities are also provided, with mappings from Quan (Deyo
    and Elixhauser versions), Elixhauser and AHRQ included.
