parseElix

logical whether to condense the result ranges to the minimal
set of parent ICD-9 codes which exactly define the list. Defaults to
<code>FALSE</code> so that the saved list will allow rapid look-up of codes
without further processing. Small memory versus time trade-off.

condense

logical whether to save the result in the source tree. Defaults
to <code>FALSE</code>.

save

path to directory to save the data. This is typically the data
folder in the devleopment source tree. Defaults to <code>"~/icd9/data"</code>.
Could possibly avoid hard-coding path with devtools functions.

path

This function uses the <code>%i9d%</code> operator, so cannot be
 done as an R file in the <code>data</code> directory. The data is documented in
 <code>datadocs.R</code>.

internal

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.
