sas_format_extract

sas_format_extract_rcomfmt

is a character vector, with one item per line, e.g. from
<code>readLines</code>

sas_lines

This is modelled entirely on a single chunk of SAS code, but hopefully can be
generalised. It relies heavily on lists and regular expression, but, as you
will see from the code, R is not a great language with which to write a SAS
parser.

list

Calculate comorbidities, Charlson and van Walraven
scores, perform fast and accurate validation, conversion,
manipulation, filtering and comparison of ICD-9 and ICD-10 codes. This
package enables a work flow from raw lists of ICD codes in hospital
databases to comorbidities.  ICD-9 and ICD-10 comorbidity mappings
from Quan (Deyo and Elixhauser versions), Elixhauser and AHRQ
included.  Common ambiguities and code formats are handled.

sas_format_extract function

<ul>
<li><code>sas_format_extract_rcomfmt</code>: Get just the <code>$RCOMFMT</code> assignment, which
 contains all the ICD (not DRG) data. The problem is <code>RENLFAIL</code> appears
 twice:
<code>"N183", "N184", "N185", "N186", "N189", "N19", "Z4901", "Z4902",
 "Z9115", "Z940", "Z992"="RENLFAIL" /*Dependence on renal dialysis*/</code>"Z4931", "Z4932"="RENLFAIL" /*Encounter for adequacy testing for
 peritoneal dialysis*/ 
so <code>RENLFAIL</code> needs special treatment</li>
</ul>
