icd9MajMinToCode

Deprecated. Single logical value which determines whether the
ICD-9 code provided is in short (<code>TRUE</code>) or decimal (<code>FALSE</code>)
form. Where reasonable, this is guessed from the input data. Use
<code>short_code</code> instead.

isShort

character vector of 'major' part of ICD-9 codes, i.e. that part
which falls before the decimal point, in decimal notation. (In five digit
notation, the 'major' part is be the first three characters (with leading
zeroes), and includes V or E prefix.

major

character vector of 'minor' part of ICD-9 codes, i.e. that part
which falls after the decimal point, in decimal notation. (In 'short' five
digit notation, the 'major' part is the first three characters including
leading zeroes which may be inferred; the last two characters represent the
'minor' part.)

minor

In debug mode, will check that <code>mjr</code> and <code>mnr</code> are same length.
