In DevikaNair90/prybar: Toolkit for Identifying Hidden PII in Text Data

Description

This function takes a vector input and searches presence of #' any text that appears to be a zipcode by looking for sequences of numbers. Specifically, it first identifies whether any string appears to be a state name or state abbreviation, then determines whether the preceding text appears to be a city in that state.

Usage

search_cities_in_states(vec, output)

search_cities_in_states(vec, output)

Arguments

vec	A vector input whose contents need to be searched for references to city names
output	The desired output of function. Defaults to "vector" where T/F vector result is returned. The argument "dt" will output a table of original vector input, T/F vector result, and the matching substring.

Details

The default output is a TRUE/FALSE vector but the function can also return a dataframe of the original vector input, the TRUE/FALSE result, and the substring that matched the zipcode pattern.
