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

Description Usage Arguments Details Examples

This function takes a vector input and searches presence of any text that appears to be a full address. 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. Once a city and state are identified, it then looks for strings that appear to be zipcodes or street addresses (meaning street name and house number).

1	search_addresses(vec, output)

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

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 address pattern.
