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

logical whether to fill out major part with zeroes, or
just truncate to the left. If E code, there is no valid code since
E800-E999 is defined. V codes could be V0x or Vxx, and so could be zero
padded.

leadingZeroes

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, 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.
