short_code
or decimal_code
The goal is to guess whether codes are short_code
or
decimal_code
form. Currently condense works, but not with the
icd
look-up table currently in use. 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_code and long are invalid, and otherwise assume
valid, even if the bulk are short_code. However, it may be more useful to
check validity after the guess.
guess_short(x_, short_code = NULL, n = 1000L, icd_name = NULL)
single logical value, TRUE
if input data are predominantly
short_code
type. If there is some uncertainty, then return
NA
.
Very quick heuristic, ploughs through ten million codes in less than one second and will stop more quickly if it finds a '.'.
