icd9GuessIsShort


partly implemented. Goal is to guess whether codes are short or
  decimal form, then to call icd9Explain with the condense argument.
  Currently condense works, but not with the icd9 lookup table currently in
  use. Not exporting this function until it works as intended. Of note,
  validation is a bit different here, since we don't know the type until
  after we guess. We could look for where both short and long are invalid,
  and otherwise assume valid, even if the bulk are short. However, it may be
  more useful to check validity after the guess.

Obsolete: 'icd9' is replaced by CRAN package 'icd'.
Calculate comorbidities, Charlson scores, perform fast and accurate
validation, conversion, manipulation, filtering and comparison of ICD-9-CM
(clinical modification) codes. ICD-9 codes appear numeric but leading and
trailing zeroes, and both decimal and non-decimal "short" format codes
exist. The package enables a work flow from raw lists of ICD-9 codes from
hospital billing databases to comorbidities. ICD-9 to comorbidity mappings
from Quan (Deyo and Elixhauser versions), Elixhauser and AHRQ included. Any
other mapping of codes, such as ICD-10, to comorbidities can be used.
