nswgeo

A collection of geospatial datasets and map plotting helpers for working with New South Wales maps. The maps are registered with cartographer and so are compatible with ggautomap.

Installation

You can install nswgeo like so:

# CRAN release
install.packages('nswgeo')

# development version
install.packages('nswgeo', repos = c('https://cidm-ph.r-universe.dev', 'https://cloud.r-project.org'))

Examples

The data can be used directly with ggplot:

library(nswgeo)
library(ggplot2)

ggplot(nswgeo::lhd) + geom_sf(aes(fill = lhd_name), show.legend = FALSE)

Alternatively, the data can be accessed through cartographer:

library(cartographer)
head(covid_cases_nsw)
#> # A tibble: 6 × 5
#>   postcode lga       lhd                 year type 
#>   <chr>    <chr>     <chr>              <int> <chr>
#> 1 2427     Mid-Coast Hunter New England  2022 B    
#> 2 2761     Blacktown Western Sydney      2021 A    
#> 3 2426     Mid-Coast Hunter New England  2022 B    
#> 4 2148     Blacktown Western Sydney      2022 B    
#> 5 2768     Blacktown Western Sydney      2021 A    
#> 6 2766     Blacktown Western Sydney      2021 B
