icd9 (version 1.3.1)

sasFormatExtract: extract assignments from a SAS FORMAT definition.

Description

this is modelled entirely on a single chunk of SAS code, but hopefully will have some generalizability. It relies heavily on lists and regex, but, as you will see from the code, R is not a great language with which to write a SAS parser.

Usage

sasFormatExtract(sasTxt)

Arguments

sasTxt

is a character vector, with one item per line, e.g. from readLines

Value

list (of lists)
