In jackwasey/icd: Comorbidity Calculations and Tools for ICD-9 and ICD-10 Codes

Description Usage Arguments Methods (by class)

Given vector of short_code or decimal ICD-9 codes, return (in the same format) those codes which are valid or invalid. Useful for generating error messages with the faulty codes if validation fails.

get_valid(x, short_code = guess_short(x))

## S3 method for class 'character'
get_valid(x, short_code = guess_short(x))

## S3 method for class 'icd9'
get_valid(x, short_code = guess_short(x))

## S3 method for class 'icd10'
get_valid(x, short_code = guess_short(x))

## S3 method for class 'icd10cm'
get_valid(x, short_code = guess_short(x))

`x`	input vector of ICD codes
`short_code`	single logical value which determines whether the ICD-9 code provided is in short (`TRUE`) or decimal (`FALSE`) form. Where reasonable, this is guessed from the input data.
