icd9GuessIsShort: guess whether short or long

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

Description

partly implemented. Goal is to guess whether codes are short or decimal form, then to call icd9Explain with the condense argument. Currently condense works, but not with the icd9 lookup table currently in use. Not exporting this function until it works as intended. Of note, validation is a bit different here, since we don't know the type until after we guess. We could look for where both short and long are invalid, and otherwise assume valid, even if the bulk are short. However, it may be more useful to check validity after the guess.

Usage

icd9GuessIsShort(icd9)

Value

single logical value, TRUE if input data are predominantly short type. If there is some uncertainty, then return NA.
