cents: Spatial points representing home locations

Description

These points represent population-weighted centroids of Medium Super Output Area (MSOA) zones within a 1 mile radius of of my home when I was writing this package.

Usage

data(cents)

Format

A spatial dataset with 8 rows and 5 variables

Details

• geo_code the official code of the zone

• MSOA11NM name zone name

• percent_fem the percent female

• avslope average gradient of the zone

Cents was generated from the data repository pct-data: https://github.com/npct/pct-data. This data was accessed from within the pct repo: https://github.com/npct/pct, using the following code:

Examples

# NOT RUN {
cents <- rgdal::readOGR(dsn = "/home/robin/npct/pct-bigdata/cents.geojson", layer = "OGRGeoJSON")
# library(geojsonio) # load with the ropensci package geojsonio if rgdal fails
# cents <- geojsonio::geojson_read(x = "~/repos/pct/pct-data/national/cents.geojson")
crs <- sp::CRS("+init=epsg:4326")
crsuk <- sp::CRS("+init=epsg:27700")
cents <- sp::spTransform(x = cents, CRSobj = crsuk)
home <- geo_code("LS7 3HB")
home <- sp::SpatialPoints(matrix(home, ncol = 2), proj4string = crs)
home <- sp::spTransform(x = home, CRSobj = crsuk)
buf <- rgeos::gBuffer(home, width = 2000)
# Check it saved the points OK
cents <- cents[buf,]
plot(buf)
points(cents)
cents <- sp::spTransform(x = cents, CRSobj = crs)
cents$geo_code <- as.character(cents$geo_code)
library(devtools)
# use_data(cents, overwrite = TRUE)
cents_sf = sf::st_as_sf(cents)
devtools::use_data(cents_sf)
# }
# NOT RUN {
