zippeR provides a set of functions for working with ZIP Codes and ZCTAs as well as building spatial and demographic data for three-digit ZCTAs. These three-digit ZCTAs have limitations (they are large regions), but they are also used within American health care to protect patient confidentiality. zippeR therefore offers researchers who must use three-digit ZCTAs the capability to download geometric data and also aggregate demographic data from five-digit ZCTAs to three-digit ZCTAs. In addition, zippeR includes functions for validating and formatting vectors of ZIP Codes or ZCTAs as well as tools for cross-walking ZIP codes with ZCTAs.
The easiest way to get started with zippeR is to install it from CRAN:
install.packages("zippeR")The development version of zippeR can be accessed from GitHub with remotes:
# install.packages("remotes")
remotes::install_github("pfizer-evgen/zippeR")The zippeR site includes dedicated articles on the following topics:
- ZIP Code and ZIP Code Tabulation Area Basics
- Converting ZIP Codes to Other Geographies
- Demographic and Geometric ZCTA Data
- Three-digit ZIP Codes and ZCTAs
