ukpolice

AppVeyor Build StatusTravis-CI Build StatusCoverage Status lifecycle

ukpolice is an R package that facilitates retrieving data from the UK police database.. The data provided by the API contains public sector information licensed under the Open Government Licence v3.0.

Installation

Install from GitHub

#install.packages("remotes")
remotes::install_github("njtierney/ukpolice")

Get the crime data with ukp_crime

ukp_crime() draws crimes from within a one mile radius of the location. When no date is specified, it uses the latest month available, which can be found using ukp_last_update().

library(ukpolice)

crime_data <- ukp_crime(lat = 52.629729, lng = -1.131592)
#> No encoding supplied: defaulting to UTF-8.

head(crime_data)
#> # A tibble: 6 x 12
#>   category  persistent_id date    lat  long street_id street_name  context
#>   <chr>     <chr>         <chr> <dbl> <dbl> <chr>     <chr>        <chr>  
#> 1 anti-soc… ""            2018…  52.6 -1.13 882346    On or near … ""     
#> 2 anti-soc… ""            2018…  52.6 -1.13 883351    On or near … ""     
#> 3 anti-soc… ""            2018…  52.6 -1.13 883408    On or near … ""     
#> 4 anti-soc… ""            2018…  52.6 -1.13 883313    On or near … ""     
#> 5 anti-soc… ""            2018…  52.6 -1.11 882420    On or near … ""     
#> 6 anti-soc… ""            2018…  52.6 -1.13 882336    On or near … ""     
#> # ... with 4 more variables: id <chr>, location_type <chr>,
#> #   location_subtype <chr>, outcome_status <chr>

ukp_last_update()
#> No encoding supplied: defaulting to UTF-8.
#> [1] "2018-03"

Specify a month and year for data

When date is specified, it must be in the format “YYYY-MM”. Currently ukp_crime() only allows for searching of that current month.

crime_data_date <- ukp_crime(lat = 52.629729, 
                             lng = -1.131592,
                             date = "2016-03")
#> No encoding supplied: defaulting to UTF-8.

head(crime_data_date)
#> # A tibble: 6 x 12
#>   category  persistent_id date    lat  long street_id street_name  context
#>   <chr>     <chr>         <chr> <dbl> <dbl> <chr>     <chr>        <chr>  
#> 1 anti-soc… ""            2016…  52.6 -1.14 882313    On or near … ""     
#> 2 anti-soc… ""            2016…  52.6 -1.12 883287    On or near … ""     
#> 3 anti-soc… ""            2016…  52.6 -1.15 883538    On or near … ""     
#> 4 anti-soc… ""            2016…  52.6 -1.13 883415    On or near … ""     
#> 5 anti-soc… ""            2016…  52.6 -1.14 883525    On or near … ""     
#> 6 anti-soc… ""            2016…  52.6 -1.14 883433    On or near … ""     
#> # ... with 4 more variables: id <chr>, location_type <chr>,
#> #   location_subtype <chr>, outcome_status <chr>

This is still a little buggy at the moment as it returns blank columns for variables like persistent_id and context, location_subtype, and outcome_status. This issue is currently logged at issue #11.

Example usage

Explore the number of crime types

library(dplyr)
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union
library(ggplot2)

crime_data <- ukp_crime(lat = 52.629729, lng = -1.131592)
#> No encoding supplied: defaulting to UTF-8.

crime_data %>%
  count(category) %>%
  ggplot(aes(x = reorder(category, n),
             y = n)) + 
  geom_col() + 
  labs(x = "Crime Type",
       y = "Number of Crimes",
       title = paste0("Crimes commited in ",crime_data_date$date[1])) +
  coord_flip() +
  theme_minimal()

Using leaflet

You can add a popup that displays the crime type using the popup argument in leaflet.

library(leaflet)
crime_data <- ukp_crime(lat = 52.629729, lng = -1.131592)
#> No encoding supplied: defaulting to UTF-8.
crime_data %>%
  leaflet() %>%
  addTiles() %>%
  addCircleMarkers(popup = ~category)
#> Assuming "long" and "lat" are longitude and latitude, respectively

Other use of ukpolice

ukpolice does other things! At the moment other features include:

  • Get crime within a polygon with ukp_crime_poly()
  • Retrieve a list of neighbourhoods for a police force with ukp_neighbourhood()

To see these examples, read the vignette “Getting Started with ukpolice”.
