Sorts lists of numeric only, V or E codes. Note that a simple numeric sort does not work for ICD-9 codes, since "162" > "1620" TODO: write tests. TODO: reply with the actual items given (not trimmed, etc.)
icd9Sort(icd9, isShort = icd9GuessIsShort(icd9))icd9SortShort(icd9Short)
icd9SortDecimal(icd9Decimal)
is a character vector or factor of ICD-9 codes. If fewer than five characters is given in a code, then the digits are greedily assigned to hundreds, then tens, then units, before the decimal parts. E.g. "10" becomes "010", not "0010".
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.
