icd9Benchmark

<code>icd9</code> package is intended to be used with large data sets, with
millions or rows. Performance of core functions is therefore of some
importance, after correctness. R package test code is for correctness,
whereas this script stresses the core functions, and looks for bottlenecks.

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.
