getInvalidDecimalIcd9

getInvalidShortIcd9

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

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,

icd9Short

given vector of short or decimal ICD-9 codes in
  <code>icd9Decimal</code> or <code>icd9Short</code>, return (in the same format) those
  codes which are invalid. Useful for generating error messages with the
  faulty codes if validation fails.

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.
