icd9ExpandRangeMajor

is a 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"

start,end

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

accepts V, E or numeric codes. Does not validate codes beyond
  ensuring that the start and end of the range are of the same type. Will add
  leading zeroes when appropriate. User can strip them out with
  icd9DropLeadingZeroes if they wish.

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.
