parseAhrqSas: parse AHRQ data

In jackwasey/icd9: Tools for Working with ICD-9 Codes, and Finding Comorbidities

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"), save = FALSE, path = "data", verbose = 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 it is used to generate data which ends up in the distributed package. However, the package user can verify that the code creates the distributed R data. Also, changes to the original SAS code can be used to regenerate the R data by the user, without waiting for a package release.
save	logical whether to save the result in the source tree. Defaults to FALSE.
path	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.
verbose	single logical value, defaults to FALSE in most functions.
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 time trade-off.
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.
