abbrev_full {campfin}R Documentation

Abbreviate full strings


Create or use a named vector (c("full" = "abb")) and pass it to stringr::str_replace_all(). The full argument is surrounded with ⁠\\b⁠ to capture only isolated intended full versions. Note that the built-in usps_street, usps_city, and usps_state dataframes have the columns reversed from what this function needs (to work by default with the counterpart expand_abbrev()).


abbrev_full(x, full = NULL, rep = NULL, end = FALSE)



A vector containing full words.


One of three objects: (1) A dataframe with full strings in the first column and corresponding abbreviations in the second column; (2) a named vector, with full strings as names for their respective abbreviations (e.g., c("full" = "abb")); or (3) an unnamed vector of full words with an unnamed vector of abbreviations in the rep argument.


If full is an unnamed vector, a vector of abbreviations strings for each full word in abb.


logical; if TRUE, then the $ regular expression will be used to only replace words at the end of a string (such as "ROAD" in a street address). If FALSE (default), then the ⁠\b⁠ regular expression will target all instances of full to be replaced with rep.


The vector x with full words replaced with their abbreviations.
