sasExtractLetStrings

is a vector of character strings, typically taken from something
like <code>readLines(someSasFilePath)</code>


Finds all the LET statements in some SAS code and writes them to
  an R list. The list item name is the SAS variable name, and each list item
  is a character vector of the contents. This is specifically for string
  assignements, but probably easy to adapter to numbers if ever needed.

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.

sasExtractLetStrings: extract quoted or unquoted SAS string definitions
