icd9DecimalToShort

character vector of ICD-9 codes. If fewer than five characters is given in a
code, then the digits are greedily assigned to hundreds, then tens, then
units, before the decimal parts. E.g. "10" becomes "010", not "0010"

icd9Decimal

character string (unit length) containing one of:
  "ignore", "silent", "warn", "stop"<p></p><p>  - <code>ignore</code> no check for validity of ICD-9 code is made implicitly.
  This is the fastest option. If the function call is explicitly to check
  validity, e</p>

invalidAction

converted decimal ICD9 code, e.g. 123.45 to 'short' e.g. 12345
  non-decimal format

manip

This package allows accurate manipulation, conversion, 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.
