Create a new column containing fractional house number data.
pm_houseFrac_parse(.data, locale = "us")
| .data | A postmastr object created with pm_prep | 
|---|---|
| locale | A string indicating the country these data represent; the only current option is "us" but this is included to facilitate future expansion. | 
A tibble with a new column pm.houseFrac that contains the fractional house number.
    If a house number is not detected in the string, a value of NA will be
    returned. If a fractional is detected in an address that has a house range associated with
    it, a new element will be added to the vector stored in pm.houseRange for the
    fractional.
