Scale_color_manual(values = c("white", "black")) Geom_text(data = HBLabel, mapping = aes(x = label_long, y = label_lat, label = Hospitals, group = NA, col = LabelOutsideBoundaries) Mutate(LabelOutsideBoundaries = HBName %in% c("Orkney", "Shetland", "Western Isles"), Summarise(label_long = mean(range(long)), label_lat = mean(range(lat)), Hospitals = mean(Hospitals)) %>% HBLabel will be the new data source for our additional layer, so it is crucial that we specify the data = argument in our geom_text() layer: map % Summarise(label_long = mean(range(long)), label_lat = mean(range(lat)), Hospitals = mean(Hospitals)) In order to have some sensible coordinates for our labels it is not a bad approach to use the mean of the range of the longitude and latitude for each Health Board, so let’s start there: HBLabel % However, seeing that the variable Hospitals is continuous and as a result of that the colour scheme is continuous also, I think it would be nice to add labels to the map showing the actual number of hospitals in each Health Board. The map we have now conveys already quite a bit of information. As the name suggests, the slot contains the actual polygons (or lines in some instances - that are used by R to draw the map. You can think of the slot as a table that stores attribute data pertaining to the geographic area of interest. These slots can be accessed using and the first two are the main interest here. Notice that we have 5 “slots” stored in NHSBoards object, namely and proj4string. shp extension, so in our case SG_NHS_HealthBoards_2018.Īt this stage it’s probably not a bad idea to have a quick look at the general structure of your Shapefile, which should look like this: ~\Projects\Shapefiles-in-R\data, and layer which is the name of the shapefile without the. The readOGR function from the rgdal package takes two arguments, dsn= (data source name) which is the folder/directory where the Shapefiles are located, e.g. NHSBoards <- readOGR(dsn = "filepath/data", In R Studio, open a new R Script and add the following: library(tidyverse)

If you haven’t done so already, unzip the Shapefiles and add them to your R project directory in an appropriately named folder. For more info on these, head over to Wikipedia.

Once you have found and downloaded the Shapefiles you are interested in, they typically come as a zip file, we can get going.Īs the very existence of the zip file possibly alludes to, a “Shapefile” isn’t actually a single file but a collection of files. Nonetheless, here is a list of websites that I find to be useful sources for Shapefiles: As per usual in this day and age, Google is your friend.

It probably depends on where you live but in many countries the respective governments provide free Shapefiles. So before we start creating maps with R we have to address one other question first: Where can we get Shapefiles for free? Geospatial data files aren’t necessarily free, in fact, a lot of service providers charge a handsome amount of money for them (after all, the generation of these files takes time, effort and money).
