parseAhrqSas: parse AHRQ data

Description

Takes the raw data taken directly from the AHRQ web site and parses into RData. It is then saved in the development tree data directory, so this is an internal function, used in generating the package itself!

Usage

parseAhrqSas(sasPath = system.file("extdata", "comformat2012-2013.txt",
  package = "icd9"), condense = FALSE, save = FALSE,
  saveDir = "~/icd9/data", returnAll = FALSE)

Arguments

sasPath

single character string containing path or URL for some SAS code. The source SAS code is stored in extdata or at the location specified in URL. In development mode in devtools, this is actually inst/extdata. This function is internal, since i

condense

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

save

logical whether to save the result in the source tree. Defaults to FALSE.

saveDir

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

returnAll

logical which, if TRUE, will result in the invisible return of ahrqComorbidAll result, otherwise, ahrqComorbid is reutrned.

Value

invisibly returns the list of vectors, where a co-morbidity name is associated with a character vector of ICD-9 codes.
