{zipcodeR} has introduced several new functions geared towards geographic applications. In this vignette we will explore these new functions and some of their typical use cases with examples.
This version introduces the new function zip_distance() for calculating the distance between two ZIP codes in miles.
zip_distance('08731','08753')
## zipcode_a zipcode_b distance
## 1 08731 08753 9.69
Users often are seeking to use zipcodeR to geocode ZIP codes. While it is possible to do this already, I have introduced a simple wrapper function that only returns that centroid coordinates of each provided ZIP code to make this process easier.
geocode_zip('08731')
## # A tibble: 1 × 3
## zipcode lat lng
## <chr> <dbl> <dbl>
## 1 08731 39.9 -74.3
You can also pass a vector of ZIP codes to geocode to quickly geocode ZIP code-level data
geocode_zip(c('08731','08721','08753'))
## # A tibble: 3 × 3
## zipcode lat lng
## <chr> <dbl> <dbl>
## 1 08721 39.9 -74.2
## 2 08731 39.9 -74.3
## 3 08753 40.0 -74.2
Given a pair of latitude / longitude coordinates in WGS84 format you can search for all ZIP codes located within a provided radius in miles. This function will default to searching within 1 mile of your provided coordinates, but can be configured to search any arbitrary radius via the radius argument.
The below code searches for all ZIP codes within 20 miles of the
search_radius(39.9, -74.3, radius = 20)
## # A tibble: 41 × 2
## zipcode distance
## <chr> <dbl>
## 1 08731 0
## 2 08757 5.28
## 3 08721 5.31
## 4 08759 5.31
## 5 08722 5.70
## 6 08005 6.90
## 7 08758 7.22
## 8 08734 7.44
## 9 08741 7.72
## 10 08755 7.84
